You don't want to miss The Swimwear Yearbook™ this summer. It’s the B2B bible for brands looking to elevate their collections and delight their consumers with fun and fresh swimwear.
WHAT ARE THE 2026 SWIMWEAR TRENDS?
According to The Swimwear Yearbook™, sustainability is one major trend for swimwear in 2026. We're ready for it: Our bio-derived LYCRA® fiber, made with 70% renewable materials, will be widely available later this year, bringing a more sustainable spandex solution to the swim segment. It delivers the same performance as our classic LYCRA® fiber with a lighter touch on the planet.
The next big swimwear trend we'll see in 2026? All things bold. Below, find a few ways we’ll see that trend expressed, and discover the LYCRA® brand products that can help bring your ideas to life.
THE BRIGHTEST BRIGHTS
Inspired by athletic swimsuits and wetsuits, 2026 swimwear promises to be eye-catching. Featuring confident color blocking and bold hues, especially pinks and reds, one-piece swimsuits — like this one from Chlore — will dominate while bikinis and other styles will remain essential.
For bold, bright suits that shape and sculpt the body just like athletic swimwear, choose LYCRA® BEAUTY fabric. Swimwear made with LYCRA® BEAUTY fabric enhances the wearer's natural silhouette, skimming curves and offering support where it's needed.
MAXIMALISM
Ready for ruffles, bows, texture, crochet details, bold patterns, and hardware, including zips and belts? It’s coming in 2026 — in droves. Next season’s swimsuits promise fun and whimsy in bold, maximalist style, like this ruffled, patterned two-piece from Empreinte.
For high-performance, wear-all-day swimwear that’s packed with personality, you need LYCRA® ADAPTIV fiber, our unique fiber that adjusts to meet the wearer’s needs.
SHINE ON
Continuing the bold theme, shimmer and shine promise to feature prominently in next season’s swimwear collections. Look for metallics — like this gold one-piece from Calarena — glitter, and sparkling fabrics, and get your go-go boots on.
To keep those sparkling suits looking their best, use LYCRA XTRA LIFE® fiber, our most durable, long-lasting spandex that keeps swimsuits looking newer for longer.
WHY CHOOSE LYCRA XTRA LIFE® FIBER?
We’ve all been there: You reach for a beloved swimsuit at the start of beach season, only to find that the spandex has lost its stretch and the suit is bagging and sagging. There’s no worse feeling. Plus, replacing worn-out swimsuits every season isn’t great for the planet.
That’s why The LYCRA Company developed LYCRA XTRA LIFE® fiber, the ultimate solution for long-lasting swimwear. We knew we had to solve the problem of spandex breakdown in swimwear once and for all.
LYCRA XTRA LIFE® fiber is a truly superior spandex offering. It’s UV and chlorine resistant, resists damage from the oils in sunscreen, and holds its shape no matter how you move. It also lasts up to 10 times longer than typical spandex, so your consumers can wear their suits again and again. Problem? Solved.
This year’s Swimwear Yearbook™ includes a feature on LYCRA XTRA LIFE® fiber, rounding up the very best swimwear from our European customers, including Chlore, Arena, Sunflair, Empreinte, Arabella London, Calarena, Anita since 1886, and more.
We love collaborating with our customers to find the perfect solutions for their products — can we partner with you next?
