The Who What Wear Swim Report Has Arrived—Here's Every Trend to Know


Just like that, it's officially swim season, and this editor couldn't be more excited about all of the cool swimsuit newness on the market for 2021. There are so many stunning trends that we've been talking about in the lead-up to summer—including everything from the three-piece swimsuits that have already taken over on TikTok and Instagram to the retro florals that are taking over—but we wanted to provide a more comprehensive guide on all things swimwear in our annual report.

Ahead, we're breaking down the biggest swimsuit trends to have on your radar and in your shopping cart for summer, featuring top picks from the most in-the-know buying experts, our team of Who What Wear fashion editors, and our very own readers. Here, get ready to dive into the best swimwear trends of 2021 that are bound to be everywhere this summer.


To get a preview of some of the most popular trends that have already been snapped up this season, I turned to our data team, who shared details about the trends our readers are loving most. It comes as no surprise that you are all tuned in to some of the coolest swimwear of 2021. More on that here.


One of the trends landing in shopping carts more than any others? Bikinis and one-piece swimsuits with super-high cuts for an elongate-leg effect. Also a favorite among celebs such as Bella Hadid and Ashley Graham, this trend is set to be really big this summer.

Cutouts are another wildly popular trend among our stylish readers. This one takes direct inspiration from the S/S 21 collections, where "naked" trends flooded the runways. More than ever, skin is in, and that is translating to swimsuits as well.

Textured fabrics were big last year, but it turns out they're gaining even more traction in 2021. Look out for standout finishes like ribbing and seersucker that add dimension to even the simplest swimsuit silhouettes.

I'm always curious to hear from fashion insiders to get their perspective on what is about to be popular, so I turned to the buyers at MyTheresa and Shopbop to share their expert insights. They have an eye into all of the fashion newness that is coming up on their sites, so it's a no-brainer to get the scoop directly from them.


According to Tiffany Hsu, MyTheresa's fashion buying director, we can brace ourselves for high-impact shades that make a major statement. "Many of this season's swimwear collections really reflect the current ready-to-wear trends," Hsu told us. "Colors are bold, metallic, or high shine. Brands to look out for are The Attico and Oséree."

Shopbop Fashion Director Caroline Maguire also weighed in about summer swim. "I cannot wait to get back into my swimsuits for the summer season," Maguire explained. "Retro-inspired silhouettes have consistently become more popular season after season. Lately, I am loving suits that provide a bit more coverage like a high-waisted bottom." As someone who is a big fan of high-rise bottoms, I'm always ready to add more to my collection.

Next, I asked Who What Wear's team of fashion editors about the top swimsuit trends they're most excited about this season. While there were plenty of others that nearly made the cut—including terry cloth bikinis and glitter swimsuits—these three were the front-runners.


Super-strappy swimsuits are simply everywhere for summer, and there are so many cool takes on them worth noting—from minimal straps you can barely see to "waist floss" versions that put the thin straps into full focus.

The three-piece swimsuit trend has already taken the fashion world by storm, and our editors can't get enough of it. To wear it, simply find a matching swimsuit set that includes a bikini and coordinating pieces (like a shirt, skirt, or scarf) in the same print.

Our senior editor Lauren Eggertsen broke the story on retro floral swimsuits, and she was certainly onto something. The throwback print is everywhere this summer and is topping our team's list of must-buy trends.
