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.
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.
Our Pick? Swim Basic Solid | Dewy Blue
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.
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.
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.
