For most swimwear sewing, I’d start with the SCHMETZ Stretch 75/11, 5-pack as the best overall pick: its fine size suits many lightweight stretch fabrics, while the stretch-needle design is made for elastic knits. The SCHMETZ Twin Stretch 2.5/75 is a standout for parallel hems, and SINGER’s assorted 80/12, 90/14, and 100/16 pack gives you more sizes to test across different fabric weights. The main tradeoff is choosing a needle fine enough to avoid visible damage but strong enough to sew through your particular layers without skipped stitches. Pack size, machine compatibility, and whether you need a single or twin needle also affect the choice. Read on for the full comparison and guidance on matching a needle to your swimwear project.

Key Takeaways
- Size 75/11 leads for lightweight swimwear: The SCHMETZ 75/11 options suit fine, stretchy fabric better than the 90/14 and 100/16 picks, which are aimed at heavier combinations.
- A stretch needle is the clearest starting point: Dedicated stretch models take priority over the jersey ball-point option when sewing elastic swimwear knits, while the jersey needle offers a different knit-focused alternative.
- Twin needles solve a specific finishing job: The two SCHMETZ twin-stretch listings are for parallel stitching, not a general replacement for a single needle.
- Assorted sizes trade simplicity for flexibility: SINGER’s 80/12, 90/14, and 100/16 pack can help when fabric weights vary, but it gives less certainty if you only sew fine swimsuit material.
- Pack format matters less than the needle inside: Several listings repeat SCHMETZ 75/11 or 90/14 needles in different packaging, so compare size and needle type before treating a card or pack count as a performance difference.

More Details on Our Top Picks
Schmetz Stretch Sewing Machine Needles, Size 75/11, 5-Pack
For lightweight swimwear knits, the 75/11 size is the main reason to choose this five-needle pack: it gives you a finer option than the Singer 90/14 Stretch Needles, which are aimed at heavier material. Schmetz specifies a medium ball point for highly elastic synthetic knits, a useful match when you want the needle to pass through stretch fabric while reducing skipped stitches. It is designed for domestic sewing machines and also lists synthetic suede as a compatible material. The tradeoff is narrow sizing: this pack does not give you a thicker needle for denser swimsuit fabric, and the product information does not include multiple sizes. Choose it for lighter fabric and a clear five-needle supply; skip it if your projects call for one pack to cover varied fabric weights.
Pros:- Medium ball point is specified for highly elastic synthetic knits.
- Size 75/11 suits lighter stretch fabrics better than the Singer 90/14 option.
- Five needles provide replacements for repeated sewing sessions.
- Compatible with domestic sewing machines.
Cons:- Only size 75/11 is included, limiting fabric-weight flexibility.
- The listed materials focus on synthetic knits and suede rather than a broad range of swimwear fabrics.
Best for: Home sewists making swimsuits or other garments from lightweight, highly elastic synthetic knits who want five matching 75/11 needles.
Not ideal for: Sewists working across both fine and dense fabrics who need multiple needle sizes in one package.
- Brand:Schmetz
- Model:SCH4022
- Size:75/11
- Quantity:5 needles
- Point type:Medium ball point
- Compatible materials:Synthetic suede; highly elastic synthetic knitwear
- Compatible device:Domestic sewing machine
Our verdict“Choose this Schmetz pack for lightweight, elastic swimwear fabric when you want five fine 75/11 needles rather than a heavier 90/14 option.”
SCHMETZ Twin Stretch Machine Needle, Size 2.5/75, 1 Count
This is the specialist pick for makers who want two parallel rows of stitching in a stretch hem, rather than a general-purpose replacement needle. SCHMETZ names spandex, Lycra, and swimwear among its compatible materials, and its large eye and groove accommodate topstitch thread. Compared with the five-needle Schmetz 75/11 pack, this twin needle is better suited to a visible, paired stitch finish, but it offers only one needle and calls for a project that benefits from twin-needle sewing. Its sharp point also differs from the medium ball point in the Schmetz single-needle pack, so fabric and machine setup matter. Pick it for planned twin-needle hems on suitable domestic machines; skip it if you need a basic needle for routine construction or several replacements.
Pros:- Designed for swimwear, spandex, and Lycra.
- Twin-needle format creates parallel rows of stitching for hems and decorative topstitching.
- Large eye and groove accommodate topstitch thread.
- Size 2.5/75 is specified for domestic sewing machines.
Cons:- Package contains only one needle.
- Twin-needle sewing requires compatible machine setup and is less versatile than a standard single needle.
- Sharp point differs from the medium ball point on the Schmetz 75/11 single-needle pack.
Best for: Swimwear sewists with a domestic machine and twin-needle capability who want parallel stitching on stretch hems or topstitched details.
Not ideal for: Beginners seeking a standard single needle, or sewists who want several needles in a pack for general swimsuit construction.
- Brand:SCHMETZ
- Model number:1774
- Size:2.5/75
- Quantity:1 needle
- Point type:Sharp point
- Compatible materials:Spandex, Lycra, swimwear
- Compatible device:Domestic sewing machine
- Thread features:Large eye and groove for topstitch thread
Our verdict“Choose this SCHMETZ twin needle for paired stretch hems on swimwear, but pick a five-pack single needle for everyday construction and replacements.”
Klasse Stretch Sewing Machine Needles, Size 75/11, 5-Pack
The Klasse pack makes sense for sewists who want a fine 75/11 stretch needle and a stated thread pairing: polyester or cotton-wrapped polyester. Its specially designed tip and scarf are intended to help reduce skipped stitches on knits, including swimwear and lingerie. Compared with the Schmetz 75/11 pack, Klasse gives more explicit guidance about thread and stretch applications, while both offer five needles in the same size. The product data lists rubber as the compatible material, so its swimwear suitability comes from the broader description rather than a detailed fabric list. That makes it a less straightforward choice for shoppers wanting material-specific guidance. Choose it if you already sew with the recommended thread types; skip it if you need several needle sizes or clearer fabric compatibility.
Pros:- Tip and scarf design is intended to help reduce skipped stitches on knits.
- Size 75/11 suits lighter stretch fabric.
- Five needles are included.
- Specifies polyester and cotton-wrapped polyester thread as suitable options.
Cons:- Only one needle size is included.
- Product specifications list rubber as the compatible material, leaving fabric guidance less clear than the SCHMETZ twin needle’s swimwear listing.
- The five-needle pack may not suit sewists who need frequent replacements across multiple projects.
Best for: Home sewists working on lightweight stretch swimwear, lingerie, or elastic who use polyester or cotton-wrapped polyester thread.
Not ideal for: Sewists needing a size range or wanting product specifications that clearly list specific swimsuit fabrics as compatible materials.
- Brand:Klasse
- Needle size:75/11
- Pack quantity:5 needles
- Compatible device:Domestic sewing machine
- Compatible material:Rubber
- Thread compatibility:Polyester or cotton-wrapped polyester
- Manufacturer part number:A5-10275
Our verdict“Choose Klasse if you sew fine stretch garments with the stated polyester thread types and want a five-pack, but look elsewhere for broader sizing or clearer fabric specifications.”
Singer 04721 Size 90/14 Stretch Sewing Machine Needles, 5-Count
Among these options, the Singer 90/14 is the heavier-gauge choice: it is aimed at spandex, Lycra, and stretchy garments such as swimsuits and yoga wear. That makes it a contrast to the Schmetz 75/11 and Klasse 75/11 packs, which are better aligned with lighter fabric. Singer includes five needles in a marked case, helping keep the size identifiable when you store other needles nearby. The listed point type is “regular point,” despite the stretch-needle description, and the compatible-material spec says woven fabric; those details make the product data less clear than SCHMETZ’s explicit swimwear and spandex listing. Choose it when a 90/14 size fits your project and you value the case, but not as a one-size-fits-all swimwear needle.
Pros:- Size 90/14 offers a heavier option than the 75/11 Schmetz and Klasse packs.
- Five needles are included in a compact case.
- Case cover is marked with the needle size.
- Description names spandex, Lycra, swimsuits, and yoga wear.
Cons:- Only size 90/14 is included, limiting use across different fabric weights.
- Listed point type is regular point, while the material specification says woven fabric, making stretch-fabric details less consistent.
- Not specified for heavy or thick fabrics.
Best for: Swimwear and activewear sewists whose fabric calls for a 90/14 needle and who want five needles stored in a size-marked case.
Not ideal for: Sewists working with very lightweight knits or looking for clearly documented point and fabric specifications before choosing a needle.
- Brand:Singer
- Model number:S04721
- Part number:S04721
- Size:90/14
- Quantity:5 needles
- Point type:Regular point
- Compatible devices:Singer, Brother, Kenmore sewing machines
- Storage:Compact plastic case with size marked on cover
Our verdict“Choose this Singer pack when your swimsuit fabric suits size 90/14 and a labeled case is useful, but favor a 75/11 needle for lighter knits.”
Singer Size 80/11 Stretch Sewing Machine Needles
At 80/11, this Singer pack sits between the finer 75/11 Schmetz and Klasse options and Singer’s heavier 90/14 set. That middle size is useful for sewists whose lightweight stretch material feels too substantial for a 75/11 but does not call for the larger 90/14. Singer names spandex and Lycra among the recommended fabrics and says the needles are designed to help prevent skipped stitches. The five-needle pack also comes in a compact, size-marked case, and the listed compatibility spans Singer, Brother, Kenmore, and other quality sewing machines. Unlike the SCHMETZ twin stretch needle, this is a standard single-needle option, not a paired-stitch tool. Its stated lightweight-fabric focus means it is not the right pick for every swimsuit material.
Pros:- Size 80/11 falls between the 75/11 and 90/14 options in this lineup.
- Recommended for lightweight stretch fabrics, spandex, and Lycra.
- Five needles are supplied in a compact case marked with the size.
- Compatible with Singer, Brother, Kenmore, and other listed sewing machines.
Cons:- Size 80/11 is specified for lightweight fabrics, limiting its use on denser materials.
- Only one size is included.
- Unlike the SCHMETZ twin needle, it cannot produce paired rows of stitching.
Best for: Home sewists using lightweight to moderate stretch swimwear fabrics who want a middle size and a clearly labeled storage case.
Not ideal for: Sewists handling heavier swimsuit fabric or seeking a twin needle for parallel hem stitching.
- Type:Stretch machine needles
- Size:80/11
- Quantity:5 needles
- Recommended fabrics:Lightweight stretch fabrics, spandex, Lycra, and suede
- Storage:Compact plastic case with size marked on cover
- Compatibility:Singer, Brother, Kenmore, and other quality sewing machines
Our verdict“Choose Singer 80/11 for lightweight swimwear when 75/11 seems too fine and 90/14 seems too heavy, but choose another format for dense fabric or twin-needle hems.”
SCHMETZ Stretch Sewing Machine Needles, Size 90/14, Pack of 5
For swimwear makers who need a straightforward needle for medium-weight stretch fabric, this 90/14 SCHMETZ stretch needle is the most balanced choice in this group. Its medium ball point and shaped eye and scarf are designed to reduce skipped stitches, a useful pairing when seams cross elastic fabric. Compared with the SCHMETZ Jersey Ball Point 80/12, this size is better suited to somewhat heavier knits, though the 80/12 is the gentler pick for lighter jersey. Five needles also make it more practical for repeat projects than the individually sold Twin Stretch model. The tradeoff is a narrower material focus: it is intended for stretch fabrics, not as an all-purpose needle. Check that 90/14 suits your fabric weight before sewing delicate swimsuit lining.
Pros:- Medium ball point is suited to elastic and stretch fabrics.
- Specially designed eye and scarf help reduce skipped stitches.
- Five-needle supply supports more than one project or replacement.
- Compatible with domestic sewing machines from all brands.
Cons:- The 90/14 size may be too heavy for delicate swimwear lining.
- Its stretch-focused design is less versatile for general-purpose sewing.
Best for: Home sewists making swimsuits from medium-weight spandex or elastic knits who want five compatible needles for a domestic machine.
Not ideal for: Sewists working mainly with very lightweight lining or woven fabrics, since 90/14 may be heavier than needed and the needle is specialized for stretch materials.
- Brand:SCHMETZ
- Needle size:90/14
- Pack quantity:5 needle cards
- Point type:Ball point
- Compatible machines:Domestic sewing machines from all brands
- Compatible materials:Elastic and stretch fabrics
- Item length:1.5 inches
- Model number:1713
Our verdict“Choose this five-pack for medium-weight swimsuit knits; pick the SCHMETZ Jersey 80/12 instead for lighter fabrics.”
SCHMETZ Jersey Ball Point Sewing Machine Needles, Size 80/12, 5 Count
The 80/12 size gives this SCHMETZ jersey needle a useful place for lighter swimsuit knits and jersey, where a heavier needle may leave more visible holes. Its rounded point is designed to pass between knit fibers rather than snagging them, which can help limit runs and uneven seams. Compared with the SCHMETZ Stretch 90/14, this is the more fabric-conscious option for lighter material, but it gives up some needle weight for thicker elastic knits. The five-count pack suits a home sewist who wants spares without stepping up to a heavier size. It is still a knit-specific needle, so it is not the choice for woven swimwear panels or mixed general sewing. Match the size to the fabric and test the stitch on a scrap first.
Pros:- Size 80/12 is a lighter option than the 90/14 stretch needles in this group.
- Rounded point helps avoid snags, runs, and holes in knit fabric.
- Designed to reduce skipped stitches and puckered seams.
- Five needles are included for replacements during sewing.
Cons:- May be too light for dense or thick swimsuit fabrics and layered elastic seams.
- Its jersey and stretch focus limits usefulness on woven materials.
Best for: Swimwear sewists using lightweight jersey, swimsuit lining, or other fine stretch knits on a domestic machine.
Not ideal for: Makers sewing thick, dense, or layered elastic fabric who need a heavier 90/14 needle, or those wanting one needle for woven projects too.
- Brand:SCHMETZ
- Needle type:Jersey ball point
- Size:80/12
- Count:5
- Compatible machines:Domestic sewing machines
- Compatible materials:Knits and stretch fabrics
- Item weight:4.54 g
- Item length:8 cm
Our verdict“Pick this pack for lightweight swimwear knits; choose a 90/14 stretch needle when your fabric is heavier.”
SCHMETZ Euro-Notions Twin Stretch Machine Needle, 4.75-Inch
When the sewing plan calls for two parallel rows in one pass, this twin stretch needle does a job the single-needle SCHMETZ 90/14 cannot. The two needles share one shank and are intended for elastic fabrics and highly stretchy knits, making the format useful for visible parallel stitching on swimwear. Its ball-point tips are meant to be gentler on stretch fibers than sharp points. The benefit comes with a narrower role: it is a single unit, not a five-pack of everyday replacement needles, and the listing specifies domestic sewing machines only. Buyers also need a machine and setup that support twin-needle sewing; that capability is not established by the product details. Compared with the regular SCHMETZ stretch pack, this is a specialist finishing choice, not the more flexible default.
Pros:- Produces two rows of stitches in one pass.
- Designed for elastic fabrics and highly stretchy knitwear.
- Ball-point construction is intended to minimize damage to stretch fibers.
Cons:- Sold as a single unit rather than a multi-needle pack.
- Requires a compatible machine and twin-needle setup.
- Its specialized twin-row function is less useful for ordinary seam construction.
Best for: Experienced home sewists whose domestic machine supports twin needles and who want parallel rows of stitching on stretchy swimwear.
Not ideal for: Beginners or sewists seeking a general-purpose replacement needle pack, or anyone whose machine is not compatible with twin-needle sewing.
- Brand:SCHMETZ Euro-Notions
- Model number:1775
- Manufacturer part number:1775
- Needle size:4.75-inch (as listed)
- Point type:Ball point
- Compatible machine:Domestic sewing machine
- Compatible materials:Elastic materials and highly elastic knitwear
- Item length:7.5 cm
- Pack quantity:1
Our verdict“Choose this only when your machine supports twin needles and you specifically want two parallel stitch rows on stretchy fabric.”
Organ Super Stretch Sewing Machine Needles, Size 90/14, 5-Pack
This five-pack is aimed at sewists working across medium-weight knits, jersey, spandex, fleece, and elastic, so it offers a broad stretch-fabric remit for a 90/14 needle. Its ball point is intended to reduce fabric damage and visible holes while helping prevent skipped stitches—useful goals for swimsuit seams, though the product description does not name swimwear specifically. Compared with the SCHMETZ Stretch 90/14, the Organ listing spells out more fabric types, including fleece and double knits; the SCHMETZ option, by contrast, specifies a specially designed eye and scarf. The main limitation is also its strength: this size targets medium-weight material, not fine lining or very lightweight swimsuit fabric. The listing gives no warranty, so buyers who value stated after-sale coverage may prefer another option.
Pros:- 90/14 size is intended for medium-weight stretch fabrics.
- Ball point is designed to reduce fabric damage and visible needle holes.
- Listed for a broad range of stretch materials, including jersey, spandex, fleece, and double knit.
- Five needles are included and the pack fits most domestic sewing machines.
Cons:- Medium-weight focus may make it unsuitable for delicate lining and lightweight knits.
- No warranty is listed.
Best for: Sewists who make swimwear alongside other medium-weight stretch projects such as jersey, spandex, fleece, or double knits.
Not ideal for: Makers sewing fine swimsuit lining or lightweight knits who need a smaller needle, or buyers who want a stated warranty.
- Brand:Hollima (product title: Organ)
- Item type:Sewing needles
- Size:90/14
- Pack quantity:5 needles
- Point type:Ball point
- Compatible machines:Most domestic sewing machines
- Compatible materials:Knit, jersey, spandex, elastic, fleece, interlock, double knit, thick jersey
- Model number:HM1178
- Warranty:None
Our verdict“Choose this pack for medium-weight stretch sewing across several fabric types, but use a lighter needle for delicate swimwear lining.”
Schmetz SCH4013 5-Piece Chrome Stretch Needle, Size 90/14
The SCH4013 is the targeted pick for highly elastic synthetic knits, including material that needs a stretch-focused needle rather than a universal option. Its medium ball point is designed to help reduce skipped stitches, making it relevant to swimwear seams where missed stitches can compromise stretch. Compared with the SCHMETZ Stretch 90/14 pack, both offer five needles at the same main size, but this listing specifically calls out synthetic suede and highly elastic synthetic knitwear. The size information is not entirely clear: it names 90/14 while also mentioning 11/75 compatibility, so buyers should verify the actual needle size in the package before sewing fine lining. That ambiguity, along with the narrow material focus, makes this a more specialized choice than the broader stretch pack.
Pros:- Specifically intended for highly elastic synthetic knits and synthetic suede.
- Medium ball point is designed to help prevent skipped stitches.
- Five needles provide replacements for ongoing sewing projects.
- Chrome finish is identified in the product title.
Cons:- Size details are ambiguous, listing 90/14 and also referencing 11/75.
- The material focus is narrower than the SCHMETZ Stretch 90/14 listing.
- No compatible-machine details are provided in the supplied specifications.
Best for: Sewists working with highly elastic synthetic swimwear knits who want a five-piece pack and can confirm the size suits their fabric.
Not ideal for: Buyers who need a clearly specified range of needle sizes or primarily sew lightweight lining and general woven fabrics.
- Brand:Schmetz
- Model number:SCH4013
- Manufacturer part number:SCH4013
- Needle size:90/14; listing also references 11/75
- Point type:Medium ball point
- Compatible materials:Synthetic suede and highly elastic synthetic knitwear
- Included components:5 stretch needles
- Package dimensions:3.75 x 0.125 x 2.25 inches
Our verdict“Consider this pack for highly elastic synthetic knits only after confirming the needle size supplied matches your swimsuit fabric.”
SINGER Stretch Sewing Machine Needles – Size 80/12, 90/14, 100/16 – 5 Pack
For swimwear sewing that ranges from lighter stretch lining to sturdier elastic fabric, this SINGER set offers more size choice than the single-size SCHMETZ Stretch 75/11 pack. It includes 80/12, 90/14, and 100/16 needles, so you can match the needle more closely to the material rather than relying on one size. The pack contains 15 needles across three five-needle packs, a practical reserve for repeat projects. Its stated compatibility with domestic machines makes it a straightforward option for home sewists. The tradeoff is that 100/16 is a heavier size than many swimwear fabrics call for, and the listing gives little detail about point or eye design. I’d choose it for varied stretch projects, not as a specialized solution for delicate swim knits.
Pros:- Three sizes allow matching needles to different stretch-fabric weights
- 15 needles provide a useful supply for repeat projects
- Made for domestic sewing machines
- Lists spandex and Lycra among compatible materials
Cons:- The 100/16 size may be too heavy for many lightweight swimwear fabrics
- Point, eye, and scarf details are not provided
- The set is focused on stretch materials rather than general sewing
Best for: Home sewists making swimwear alongside stretch projects in several fabric weights who want three needle sizes in one set.
Not ideal for: Sewists working only with fine swimwear knits who want a clearly specified ball point and a single lighter size.
- Brand:SINGER
- Model:N2045
- Quantity:15 needles (3 packs of 5)
- Needle sizes:80/12, 90/14, 100/16
- Compatible machines:Domestic sewing machines
- Compatible materials:Spandex, Lycra, suede
Our verdict“Choose this SINGER set if your swimwear and stretch projects vary in fabric weight; choose a specified 75/11 stretch needle for consistently fine knits.”
SCHMETZ Stretch Sewing Machine Needles, 75/11, 5-Pack
The 75/11 size makes this SCHMETZ pack a focused choice for lighter, highly elastic swimwear fabrics. Its medium ball point is intended for elastic materials, while the specially designed eye and scarf are meant to help reduce skipped stitches—a useful feature when stretch fabric shifts or flexes as it is sewn. Compared with the multi-size SINGER set, this pack gives up weight options but makes the choice simpler if you mainly sew fine knits. It also offers the same stated size and needle design as the five-needle cards in the SCHMETZ 5-card pack, but this listing describes just five needles total. The limitation is narrow sizing: thicker fabric or heavier elastic may call for another needle size, and the listing provides no broader multipack supply.
Pros:- 75/11 size suits many lightweight stretch fabrics
- Medium ball point is designed for elastic materials
- Eye and scarf design aims to reduce skipped stitches
- Compatible with domestic sewing machines
Cons:- Only one needle size is included
- Five needles offer less supply than the SCHMETZ five-card pack
- May not suit heavier fabrics or thicker elastic as well as larger sizes
Best for: Swimwear makers who mostly sew lightweight, highly elastic knits and want a clearly specified 75/11 needle.
Not ideal for: Sewists alternating between delicate lining and heavier swim fabrics who need multiple needle sizes in one purchase.
- Brand:SCHMETZ
- Quantity:5 needles
- Needle size:75/11
- Needle system:130/705 H-S
- Point type:Medium ball point
- Compatible materials:Elastic materials and highly elastic knitwear
- Compatible machines:Domestic sewing machines
- Manufacturer part number:1722
Our verdict“Pick this pack for light, elastic swimwear knits; choose the SINGER multi-size set if your projects span a wider range of fabric weights.”
SCHMETZ Knit, Stretch, NonStick, Denim, and Universal Sewing Machine Needles
This SCHMETZ assortment is the broadest-use option here, but it is not the most direct swimwear buy. It includes a stretch needle alongside NonStick, Jeans, and Universal types, so it can cover sewing and craft jobs beyond elastic fabric. The NonStick needle is designed to resist glue and fusible residue, while the reinforced Jeans needle is aimed at heavier work. Compared with the dedicated SCHMETZ 75/11 packs, this set sacrifices a clearly stated run of stretch needles for versatility across unrelated tasks. The available sizes also do not specify a size for the stretch needle, making it harder to match precisely to swimsuit fabric. I’d choose it for a sewing drawer that needs varied needle types, but skip it if your main goal is a predictable supply for swimwear construction.
Pros:- Includes a stretch needle among several useful needle types
- NonStick needle is designed to resist glue and fusible residue
- Reinforced Jeans needle is intended for heavier sewing
- Universal needles add general-purpose coverage
Cons:- Quantity of needles in the set is not specified
- Stretch needle size is not identified in the supplied details
- Most of the assortment is not specific to swimwear sewing
Best for: Sewists who make occasional swimwear but also need needles for denim, general sewing, and adhesive-heavy craft projects.
Not ideal for: Swimwear specialists who need a known quantity and size of stretch needles for repeated work.
- Brand:SCHMETZ
- Model:1853
- Needle types:Super NonStick, Jeans, Universal, and stretch
- Listed sizes:Super NonStick 80/12; Jeans 90/14; Universal 70/10, 80/12, 90/14
- Compatible machine:Domestic sewing machine
- Compatible materials:Knit and stretch fabrics
- Item weight:4.54 g
Our verdict“Choose this assortment for mixed sewing needs with occasional stretch work, not when you need a clearly specified swimwear needle supply.”
SINGER 2045 Stretch Sewing Machine Needles, Size 90/14, 10-Pack
If you prefer a larger needle for sturdier stretch fabric, this SINGER pack supplies ten 90/14 ball-point needles in one size. That makes it more focused than the SINGER assortment of 80/12, 90/14, and 100/16 needles, while still offering more needles in the chosen size than the five-count SCHMETZ 75/11 pack. A ball point is a relevant feature for knit construction, and domestic-machine compatibility suits common home setups. The listing names cotton, linen, polyester, and rayon as compatible materials, but does not specifically list spandex or swimwear fabric; that leaves less direct material guidance than the SCHMETZ stretch models. The single size also limits flexibility for fine lining. I’d consider it for firmer stretch layers, rather than as my first pick for delicate swimsuit knits.
Pros:- Ten needles provide a larger supply than a five-needle pack
- 90/14 size is suited to projects that need a sturdier needle
- Ball point is appropriate to knit sewing
- Compatible with domestic sewing machines
Cons:- Only one size is included
- Listed compatible materials do not include spandex or swimwear fabric
- Less suited to very fine knits than a 75/11 option
Best for: Home sewists who regularly use 90/14 needles on firmer stretch fabrics and want ten replacements in one size.
Not ideal for: Makers sewing mostly lightweight swimwear lining or seeking explicit guidance for spandex and elastic knits.
- Brand:SINGER
- Model:2045
- Quantity:10 needles
- Needle size:90/14
- Point type:Ball point
- Compatible machines:Domestic sewing machines
- Compatible materials:Cotton, linen, polyester, rayon
Our verdict“Choose this pack for repeat sewing with 90/14 needles on firmer stretch layers, but favor a 75/11 SCHMETZ pack for lighter swimwear knits.”
SCHMETZ Stretch Sewing Machine Needles, Size 75/11, 5-Needle Cards, Pack of 5
For someone sewing swimwear regularly, this SCHMETZ option supplies 25 needles in size 75/11, giving it a different purpose from the single five-needle SCHMETZ 75/11 pack. Both listings describe a medium ball point and a specially designed eye and scarf intended to help reduce skipped stitches; this pack’s advantage is the larger quantity, not a different needle design. Its stated material range includes elastic knits and stretch wovens, with examples such as spandex and minky, which makes the fit for flexible fabrics clearer than the SINGER 90/14 multipack. The tradeoff is that every needle is the same lighter size. It is less adaptable than SINGER’s three-size set when fabric weight varies, and the specialized design is not a general-purpose choice for woven repairs.
Pros:- 25 needles provide a larger supply than the five-needle SCHMETZ pack
- 75/11 size targets lighter stretch fabrics
- Ball point and eye-and-scarf design aim to reduce skipped stitches
- Lists elastic knits and stretch wovens as compatible materials
Cons:- All needles are the same size, limiting fabric-weight flexibility
- Specialized for stretch fabrics rather than general sewing
- A large supply may be unnecessary for occasional swimwear projects
Best for: Frequent swimwear makers who use 75/11 needles consistently on elastic knits and want a substantial replacement supply.
Not ideal for: Occasional sewists or makers who need larger sizes for heavier fabric, or general-purpose needles for woven projects.
- Brand:SCHMETZ
- Needle size:75/11
- Quantity:5 cards, 5 needles per card
- Point type:Ball point
- Compatible materials:Elastic knits and stretch woven materials
- Compatible machines:Home sewing machines
- Model number:4337008852
- Manufacturer part number:1722
Our verdict“Choose this pack for repeated sewing of fine elastic swimwear fabrics; pick the SINGER multi-size pack if you need more size flexibility.”
How We Picked
I ranked these needles by how directly their stated type and size fit common swimwear sewing needs: elastic knits, fine fabrics, layered seams, and stretch hems. Dedicated stretch needles in sizes 75/11 and 80/12 earned the strongest position for lightweight swimsuit material; heavier 90/14 and 100/16 options sit lower unless a project calls for thicker layers. Twin-stretch needles were judged for their narrower role in parallel hems, while the jersey ball-point and mixed-type assortment were considered for their broader knit or multi-project use.
I also weighed how clearly each listing communicates what a buyer is getting, including size, count, and whether it is a single or twin needle. Repeated SCHMETZ listings with the same size and needle type are not treated as meaningfully different sewing solutions just because the packaging differs. I gave more weight to a predictable match for swimsuit fabric than to a broad assortment, and I accounted for machine compatibility and the fact that needle choice still needs to be verified with a scrap of the actual fabric.

Factors to Consider When Choosing Stretch Needles For Swimwear
Choosing a needle for swimwear is less about buying the heaviest-duty option and more about matching the point and size to the fabric, thread, seam layers, and machine. These broader checks can help prevent skipped stitches, snags, and unnecessary needle changes.
Match the needle size to fabric weight and layers
Lightweight swimsuit fabric often calls for a finer needle, which is why 75/11 and 80/12 options make sensible starting points in this roundup. A larger 90/14 or 100/16 may be useful when seams include bulky elastic or several layers, but a larger needle can leave more visible holes in fine material. Don’t choose by the fabric name alone: lining, elastic, and seam allowances change the thickness the needle must pass through. Test on a layered scrap assembled like the real seam rather than on a single fabric layer. If stitches skip, check threading and tension before moving up a size automatically. A size change can address penetration, but it cannot correct every cause of poor stitches.
Choose stretch or jersey for the knit you are sewing
A dedicated stretch needle is the most direct match among these listings for highly elastic swimwear fabric. A jersey ball-point needle is designed for knit fabrics too, but it is not interchangeable with every stretch-needle application; fabric construction and machine behavior matter. Buyers often assume that any needle labeled for knits will handle swimsuit material equally well. Start with the needle type most closely matched to a slick, elastic fabric, then compare a jersey option only if a test seam suggests it works better. Inspect the fabric after stitching for pulled yarns or small holes, not just the appearance of the thread line. The right choice is the one that forms clean stitches without damaging the test fabric.
Treat twin needles as a hemming tool, not an all-purpose upgrade
A twin stretch needle can create two parallel rows of stitching in one pass, making it useful for a finished-looking hem on suitable machines. It does not replace a single stretch needle for ordinary seams, and its use depends on the machine’s needle plate, presser foot, threading setup, and stitch options. Check the machine manual before buying or installing one; the needle spacing and machine clearance must be compatible. Twin stitching can also behave differently on highly elastic fabric, so test the hem with the same thread and fabric layers planned for the garment. If your main need is seam construction rather than parallel topstitching, a single needle is the more versatile choice. The two twin listings differ in stated size or presentation, so verify the exact specification before ordering.
Consider thread, stitch, and seam stretch together
A suitable needle cannot make a rigid stitch stretch enough for a swimsuit seam. The sewing machine’s stitch choice, thread, tension, and seam construction all affect whether stitching can move with the fabric. A narrow zigzag or another stretch-capable stitch may be more appropriate than a straight stitch for seams that need to flex. Before changing needle size, confirm that the thread is compatible with the fabric and that the machine is threaded correctly. Use a scrap to test the seam under gentle stretch, checking for popped stitches as well as needle holes. This avoids buying a larger or different needle to solve a problem caused by stitch setup.
Buy for the work you actually do, not the largest assortment
If you sew mostly lightweight swimwear, a focused pack of 75/11 or 80/12 needles is easier to match to the task than a broad size assortment. Mixed sizes make more sense if you also sew thicker knits, layered activewear, or other projects that need different needle weights. Pack counts and packaging can be misleading when several listings contain the same size and type; compare the needle specification first. A larger pack can be convenient for frequent sewing, but it does not add value if the needle size is wrong for your fabric. Keep different sizes labeled and replace a needle when it becomes blunt or damaged. For beginners, one clearly specified size plus a fabric-scrap test is usually a simpler starting point than buying several types at once.
Check machine compatibility and test before sewing the garment
Needle systems and machine requirements vary, so confirm that the listed needle fits your sewing machine before purchase. Twin needles need an additional compatibility check because the machine must accommodate the needle width and threading arrangement. Even a suitable needle can produce poor results if it is installed incorrectly, bent, or past its useful life. Before sewing a swimsuit, make a test seam with the same fabric, lining, elastic, thread, and stitch settings. Look at both sides of the fabric and stretch the seam gently to spot skipped stitches or damage. This short test can save fabric and help distinguish a needle mismatch from a setup issue.
Frequently Asked Questions
Which size should I try first for lightweight swimsuit fabric?
I would begin with a 75/11 or 80/12 stretch needle for lightweight swimsuit fabric, then test it on a scrap with the same layers as the garment. The 75/11 SCHMETZ options lead this roundup for fine material, while the 80/12 choices offer another nearby size to compare. If the needle struggles through a bulky elastic join, test a larger size on a separate scrap rather than using it across the whole garment. Check for skipped stitches and visible holes after gently stretching the seam. Fabric weight and construction matter more than a single size recommendation.
Can I use a jersey ball-point needle instead of a stretch needle for swimwear?
Sometimes, but I would not treat the two types as automatic substitutes. The SCHMETZ jersey ball-point listing is intended for knit fabrics, while the dedicated stretch options are the more direct starting point for highly elastic swimsuit material in this roundup. The best choice depends on how the needle interacts with your particular fabric and machine. Test both types on scraps if the first one skips stitches or marks the fabric. Keep the needle that makes clean stitches under gentle stretch without damaging the knit.
Do I need a twin stretch needle to hem a swimsuit?
No; a twin stretch needle is optional and is useful when you want two parallel rows of stitching and your machine supports the setup. A single stretch needle is more versatile for construction seams and can also be used for many hemming approaches. Before buying a twin needle, check your machine manual for needle-width limits, foot and plate clearance, and threading instructions. Twin stitching should be tested on the actual fabric because very elastic material can affect how the hem lies. If you mainly need reliable seams, choose a single needle first.
Should I choose a 90/14 needle for swimwear elastic and layered seams?
A 90/14 can be worth testing where elastic or several layers make the seam thicker, and this roundup includes multiple 90/14 stretch choices. It is not automatically the right needle for the whole swimsuit, especially when the main fabric is thin and can show larger holes. Try it on a layered scrap and compare the result with a finer 75/11 or 80/12 needle. Look for clean penetration, balanced stitches, and no obvious damage after stretching. If the finer needle sews the layers reliably, there may be no reason to size up.
How do I decide between a focused needle pack and an assortment?
A focused pack is the simpler choice if you mostly sew lightweight swimwear and already know that a particular size works for your fabric. The SINGER assorted 80/12, 90/14, and 100/16 pack is more useful if you also sew thicker knits or expect to test several fabric weights. An assortment can reduce repeated purchases, but it does not guarantee that every size will suit swimsuit fabric. Compare the exact needle types and sizes, since several listings in this roundup repeat the same SCHMETZ specification in different packaging. If you are unsure, start with one likely size and test it before expanding your collection.
Conclusion
For most sewists choosing stretch needles for swimwear, I’d pick the SCHMETZ Stretch 75/11, 5-pack as the best overall starting point for lightweight elastic fabric. The best value depends on the size you already know works: among the repeated 75/11 listings, choose the pack format that suits your storage and sewing frequency rather than assuming the packaging changes performance. For a more flexible size range, SINGER’s assorted 80/12, 90/14, and 100/16 pack is the stronger multi-project pick; for beginners, a clearly specified 75/11 or 80/12 single-size pack keeps testing straightforward. Sewists who want parallel hems should choose a compatible SCHMETZ Twin Stretch, while those sewing thicker elastic layers can test a 90/14 option. I’d match the needle to a fabric scrap before sewing the garment, since machine setup and fabric construction can change the result.
