One-Piece vs Tankini: Which Swimsuit Style Suits You?

Standing in front of a wall of swimsuits and not sure where to start? The right style comes down to how you actually plan to use it — lounging poolside, swimming laps, or something in between. Here's how to choose between a one-piece and a tankini, plus a few specialty styles worth knowing about.

One-Piece: Best for Active Days and Full Coverage

A one-piece swimsuit is the most versatile option in your closet — supportive, secure, and built to move with you. Our Ruched Solid One-Piece Swimsuit is a classic, flattering choice for everyday beach days, while the Racing Padded One-Piece is built for actual laps, with padded support and a sleeveless, streamlined cut.

If full coverage and comfort are your priority, the Tummy Control Swimsuit offers a smoothing, conservative fit without sacrificing style, and our Sports One-Piece – Plus Size is designed specifically for a flattering, supportive fit at every size.

Tankini: Best for Comfort and Versatility

A tankini gives you the coverage of a one-piece with the flexibility of two pieces — easier bathroom breaks, more length options, and a relaxed, tank-top-style fit. Our Floral Sport Tankini Set pairs a tank-style top with boxer-brief bottoms for coverage that still feels sporty and put-together, making it a great choice for the beach, the lake, or a pool day with kids.

Long-Sleeve & Full-Coverage Options

If sun protection or extra coverage matters most, a long-sleeve style is worth considering. Our Long-Sleeve Zip Swimsuit is built for active days in the water — think surfing, paddleboarding, or simply avoiding sunburn on a long beach day — without compromising on style.

How to Decide

• Swimming laps or being very active? Go with a padded, sleeveless one-piece for support and range of motion.
• Want max coverage without feeling restricted? A tummy-control one-piece or a tankini both work well.
• Prioritizing comfort and easy changing? A tankini's two-piece construction makes bathroom breaks and quick changes simpler.
• Spending hours in the sun? A long-sleeve style protects your skin without extra sunscreen reapplication.

There's no single "best" swimsuit style — just the one that fits how you actually spend your day at the water. Shop the full Swimwear collection to find yours.
