Creating your own swimwear is an exciting project, but choosing the right fabric is key to getting a comfortable, stylish, and long-lasting swimsuit. Whether you’re sewing a bikini, one-piece, or rash guard, the fabric you choose will determine how well it fits, stretches, and holds up to all your activities.
What to Look for in Swimwear Fabric
Swimwear fabrics need to be:
Stretchy: Look for at least 50% four-way stretch to ensure a snug, comfortable fit.
Quick-drying: Fabrics that hold moisture will feel heavy and uncomfortable.
Durable: Strong fibres prevent sagging and wear.
Top Fabrics for Swimwear
Nylon Spandex (Polyamide Spandex)
If you’re looking for a classic, go-to swim fabric, this is it! Nylon spandex is soft, stretchy, and fits like a dream. It moves with your body and gives that smooth, second-skin feel—perfect for bikinis, one-pieces, and even swim leggings.
Pros: Soft, lightweight, and dries quickly
Cons: Slightly less chlorine-resistant than polyester blends
Stretch: 4-way | 80-90% cross-grain and straight-grain
Polyester Spandex
If you’re planning to swim a lot—as in, lap after lap in the pool or back-to-back beach days—this is the fabric you need. Polyester spandex holds up like a champ against chlorine and UV rays, meaning your swimsuit will stay vibrant and stretchy for the long haul.
What we’d grab? Swim Print | Porcelain Rhapsody. This print has such a soft romantic vibe and just the right amount of stretch to keep things comfy.
Why you’ll love it: Long-lasting, fade-proof, and feels great against the skin.
Keep in mind: It’s not as silky-soft as nylon, but it makes up for it with durability.
Textured Swim Fabrics
Want to take your DIY swimwear to the next level? Textured fabrics are where it’s at. Whether it’s ribbed, waffled, or jacquard, these fabrics add a unique, high-end look to your swimsuit.
What we’re obsessed with?Swim Basic Rib | Marine. Navy is a timeless, elegant color that never goes out of style.
Why you’ll love it: Looks stylish, fits like a glove, and makes your DIY swimsuit feel designer-level.
Pro tip: Ribbed swim fabric provides amazing compression by hugging the body with its structured texture, creating a flattering and supportive fit.
Don’t Forget the Lining!
No one wants a see-through swimsuit, right? For a pro finish, always add a good lining. It keeps things secure, adds comfort, and makes sure your swimsuit lasts!
What we’d use? Swim Lining | Nude . It’s lightweight and stretchy enough to move with you.
Why you’ll love it: Gives your swimsuit that polished, high-quality feel.
Pro tip: Use Power Mesh if you're looking for tummy control in a one-piece!

Mistakes to Avoid When Sewing Swim Fabric
Making your own swimsuits can be an incredibly rewarding hobby, but it’s also easy to make mistakes, especially if you’re just starting! Not gonna lie; we’ve all been there. For this blog, we’re highlighting some common sewing mistakes when working with swim fabrics—we also have some fab recommendations to help you get through it so you can rock that beachwear in style!
1. Stop That Stitch! Are You Using the Right Needle?
Using a ballpoint needle is important when sewing swim fabrics like Swim Print | Mint Blossom. It avoids unpleasant snags and keeps your fabric in tip-top shape.
2. Grainlines Are Your Best Friends
Let’s talk about grainlines. Cutting on the wrong grain can lead to garments that hang oddly. Always mind the grain, especially when working with fabrics like the Swim Kit | Coco Tweed.
3. Pre-Wash and Prep Your Fabrics!
Always pre-wash your fabric to avoid any size surprises. And remember to follow the wash instructions, you don’t want to see the cute French Terry | Bamboo - Vanilla losing shape after you’re done sewing!
4. Seam Allowance
Seam allowances are the secret to sleek finishes and a well-fitting garment. Patterns for swim projects—like the one you’ll need for the Swim Kit | Floral Rush + Wildberry—include specific seam allowances, so let’s give them the respect they deserve.
5. Thread Drama? Choose Quality for Smooth Sewing!
Cheap or old thread just won’t cut it. High-quality threads are key when sewing swimsuit fabric, especially pieces like the ones in our Swim Kit | She’s An Icon + Black—which, by the way, already includes some top-quality Gütermann thread!
6. Test Garment First
Before you cut into your precious fabric, make a test garment. Try using a less fancy fabric before handling your awesome Swim Kit | Grey Leopard + Black.
7. Steam Power!
Press your seams and hems as you go. For swim fabrics like Swim Print | Baroque Silhouette, use a pressing cloth and low heat to avoid damaging the fabric!
8. Maintain the Right Tension
Make sure your sewing machine’s tension is set correctly. Play around with a scrap piece of stretchy fabric from the Swim Print | Spot On to get it just right.
9. Keep Your Scissors Sharp
Using dull scissors is a no-go. Sharp tools are essential, especially with designs like Swim Print | Gilded Flora.
10. Sew Slow and Steady
Rushing through your projects is a recipe for frustration. Trust us, patience pays off. Take your time and enjoy the process while working with Swim Kit | Life’s A Peach + Forest Green or another kit.
11. Study Your Pattern
Always read through the entire pattern instructions. It clarifies everything, especially with fab kits like the Swim Kit | Lost In Lagos + Navy.
12. Tune into Your Fabric’s Mood
Each fabric has its personality. Some fabrics like our Swim Print | Check it Out have unique stretch and thickness, so adjust those techniques accordingly.
13. Use the Right Stitches
Different fabrics require different stitches. Zigzag stitches are amazing for swim fabrics like Swim Print | Sleepy Hollow.
14. Handle with Love
Delicate fabrics like swim ones need a gentle touch. Use special needles and take your time with the Swim Kit | Garden Whimsy.
By mindfully following these tips and tricks, sewing swimsuit fabrics can be fun and fabulous! Check out our Swim 2025 Collection and our Swim Kits Collection to get your fabrics and kits.

If effortless style had a fabric soulmate, it would be linen. It’s breathable, lightweight, and has that “Oh, this old thing? Just threw it on” kind of elegance. Whether you’re making an oversized button-up, a tailored jumpsuit, or an easygoing sundress, linen just gets the job done.
Our pick? Woven | Viscose + Linen - Lavender. It’s structured yet soft, perfect for anything from power dressing to weekend lounging.

What’s in our cart? Cotton Stretch Print | Night Garden. Crisp, breathable, and features a stunning black and white floral design that screams spring (without actually screaming, of course).
4. Lightweight Cotton—Your Everyday Go-To
Yes, cotton is a staple. But not all cottons are created equal. This season, it’s all about breathable, soft, move-with-you cottons that work for everything from breezy blouses to laid-back dresses.
Our cotton crush? Cotton Poplin Print | French Botanicals. Playful, fresh, and just structured enough to hold its shape without feeling stiff.
✔️ Lightweight and breathable✔️ Perfect for relaxed silhouettes—think wrap skirts, shirtdresses, and flowy tops
5. Stretchy Ribbed Knits—Because Who Said Comfort Can’t Be Chic?
Soft, stretchy, and just the right amount of form-fitting, ribbed knits are the real MVP this season. They hug your curves (without suffocating you) and work for everything from cute crop tops to lounge sets.
Must-have? Ribbed Knit | Bamboo - Fuchsia —the ideal balance of cozy and stylish.
6. Sheer and Flowy Chiffon—For Those Drama-Queen Moments
Not all heroes wear capes, but if they did, they’d probably be made of chiffon. Whether you’re layering it over another fabric or making a billowy blouse that catches the breeze just right, this fabric brings instant romance to any project.
Our go-to? Chiffon | Midsummer Night—light, sheer, and practically made for twirling.
✔️ Adds a soft, dreamy aesthetic✔️ Perfect for layering or statement pieces
