Compare the best one-piece swimsuits from top stores in one place.

One-piece swimsuits here range from about $10 to $745. Styles include halter, plunge, paillette, wrap and bandeau designs, with materials such as nylon, polyester, sequin-covered fabrics and double-face wool blends for luxury options.

When picking a one-piece, look for a supportive built-in bra or molded cups, adjustable straps and a secure back closure. Fabrics with chlorine resistance are best for pool use, while smoother finishes suit beachwear.

Consider the cut, a plunge or deep-V offers a sleek silhouette, while a high-neck provides more coverage. Check for lining and reinforced stitching to ensure durability.

Questions

How do I choose the right size for a one-piece swimsuit?

Measure your bust, waist and hips, then compare to the brand’s size chart; many brands recommend sizing up for a tighter fit.

Do one-piece swimsuits provide enough support?

Look for built-in bras, molded cups or underwire for added support, especially if you need more lift.

Can I wear a sequin one-piece in the pool?

Sequined fabrics are usually decorative and may not hold up well to chlorine; choose a plain version for regular pool use.

How should I care for my one-piece swimsuit?

Rinse in cool fresh water after each use and hand wash with a gentle detergent; avoid wringing and direct sunlight to preserve color.
