Once again, you can thank athleisure for this comfort-focused trend.


Athleisure seems to be making an impact in almost every fashion category these days, from denim to lingerie. Next up: swimwear. Bikinis have been the fashion-forward standard for years, but as more and more women want to be active in their bathing suits, one-pieces have grown majorly in popularity. Throw the Kardashian-Jenner clan and friends wearing them on the reg and the upcoming Baywatch movie into the mix, and it's easy to understand why they're on the rise. In fact, it looks like this summer might finally be the season when one-pieces overtake bikinis. (Related: This Multifunctional Athleisure Swim Collection Is Genius)

How do we know this? Retail analytics firm EDITED determined that there are more one-piece styles available online right now than last year (20 percent more!), and the bikini options online have decreased by 9 percent. Plus, one-piece swimsuits are selling out (as in, flying off the shelves until there are none left!) *three* times faster than they did in 2016. This time last year, it took an average of 106 days for a one-piece swimsuit to sell out. This year? Just 37 days. That's a pretty huge difference.

Another significant detail is that the most-stocked one-piece brands are actually active ones. Dolfin, Speedo, TYR, Nike, and Arena are most stocked in the U.S., and Adidas is the top brand in the United Kingdom. More than anything, this shows that the demand for swimwear women can actually do laps and crash waves in is seriously high. (Getting the hang of pool-based sweat sessions?

Of course, this obviously doesn't mean that bikinis are "out," just that one-pieces are trending majorly. "While you don't need to put your bikinis into storage this season, the one-piece has made an explosive comeback this year," says Emily Bezzant, Head Analyst at EDITED. "It's not surprising due to current trends and our quest for comfort," she adds. It's true that in the age of yoga pants, women are demanding more comfort from their clothes, so it makes sense that this would extend to beach wear, too. So whether you're looking for a sporty suit to crush your pool workout or something a little more fashion-forward for lounging, it's safe to say you'll have more options than ever before.
