Compare the best one-pieces from top stores in one place.

One-piece swimsuits on this page cost between $52 and $329. Styles include bright stripes, solid colors, seersucker, corduroy, reversible patterns and keyhole cutouts, using fabrics like polyester, spandex, cotton blends and lightweight knits.

When choosing, check for adjustable straps or ties, a comfortable lining, and UV-protective fabrics if you’ll be in strong sun. Reversible designs give two looks in one, while textured fabrics such as seersucker add breathability.

Fit matters, look for a suit that supports your bust, offers the coverage you prefer, and has easy-care instructions. Some pieces have removable pads or built-in support for extra confidence.
