Hi, hello! We’re so glad you made your way down here, so we can tell you a little bit more about our amazing one-piece swimsuits. In fact, one-piece swimsuits are how Summersalt got started. We debuted our first collection of one-piece swimwear in 2017, and we’ve been working hard (while having fun) to bring you new colors, prints, & silhouettes ever since. Whether you’re looking for a classic halter or modest one-piece swimsuit, the Summersalt lineup is designed to have something for everybody. That’s why our one-pieces come in sizes 0-22 (shop the Sidestroke for sizes 0-24) and many come in long torso sizes, too. So go ahead — dive in and find your new favorite today.

At Summersalt, our one-piece swimsuits are crafted with the same signature compression fabric that started it all—offering 4x the compression and 5x the strength of typical swimwear for a sculpting, confidence-boosting fit. Each silhouette is developed using our data-backed approach, built from 1.5 million measurements from 10,000 real women, so you can trust the fit feels as good as it looks. From best selling asymmetrical styles like The Sidestroke to classic scoop necks, plunging V-necks, and sporty zip-front designs, our one-piece swimwear blends fashion-forward details with everyday functionality.

Thoughtful features like built-in shelf bras, adjustable straps, full-coverage bottoms, and long-torso options ensure support where you want it most. Looking for tummy-control one-piece swimsuits, supportive suits for fuller busts, or sleek styles perfect for lap swimming? You’ll find versatile options designed for beach vacations, pool days, and everything in between. Made with recycled materials and designed to hold their shape swim after swim, our women’s one-piece swimsuits deliver durability, sustainability, and standout style—all in one effortless suit.
