25 Best One-Piece Swimsuits, According to Reviewers & Glamour Editors

This Boden one-piece fits according to your cup and measurements so you can get the most support—and coverage—for the girls. The Kate Middleton–beloved brand is a top pick for Glamour editors, too, and who could blame us? Pair this pretty suit with a red lip for the total 1950s pinup look.

This is my all-time favorite bathing suit,” says Glamour’s Schwartz. “It took decades to find a one-piece that could give me the same support, lift, and shape as a bikini top or a bra, so when I found Boden, I haven’t looked back. (It’s rare to find a one-piece that comes in cup sizes which means something is always off). It comes in a variety of different prints, from tropical to preppy, and they wash so well without fading. Plus, they’re actually comfortable—no painful boning—and keep me sucked in. I’ve turned all of my friends on to them, too, and now they’re converts as well.”
