The best one-piece swimsuits are hardly a bore. Ranging from minimal and sleek to sexy as your bittiest bikinis, they qualify as more than cute swimwear. The best one-piece swimsuits are eternally stylish staples for those who prefer more coverage, are often active in the water, or need a suit that can keep up with busy-as-can-be kids.
“One-piece swimwear is a key category where we see interesting developments, season after season,” Liane Wiggins, head of womenswear at MatchesFashion, tells Bazaar. From established labels to new swimwear brands, Wiggins says, designers like Johanna Ortiz, Louisa Ballou, and Christopher Esber are “transforming the one-piece swimsuit into a luxury fashion item that can easily integrate into our everyday summer wardrobe, rather than being a vacation-only item.” Still, the classics remain coveted. “Purchasing a high-quality one-piece swimsuit from the likes of Eres, Bottega Veneta, or Lisa Marie Fernandez is one of the best investments that women can make,” Wiggins notes.
Whatever your taste, Wiggins says, “amazing quality fabric and a cut that works for individual body shapes is key to help women feel sexy, empowered, and confident.” To curate Bazaar’s edit of the best one-piece swimsuits, we considered Wiggins’s expert recommendations, along with shopper reviews and our own swimwear tests. Ahead, shop 25 one-piece swimsuits that made the cut, featuring everything from clean lines and cutouts galore to romantic detailing and monogram logos.

What reviewers are saying: “I struggle to find one-piece suits that fit my long torso—even long-torso suits often don’t work for me. I took a gamble on this (sized up one size from my usual) and so happy I did. It’s super flattering, stays on well, and fits great (no wedgies or low boobs, as my long-torso gals can probably relate to). It’s the cool, non-mom-ish one-piece of my dreams.”

What reviewers are saying: “I loved this one-piece so much, I didn’t want to take it off. I loved that it didn’t dig into my hips, but just created a smooth profile. If I could take off a half a star it would be for the fabric under the armpits, which is a little pleated/wrinkled. It may be because I’m smaller on top than on the bottom. But it still looks amazing!”
