Racerback one-pieces are your best bet.

Yes. For athletic builds, look for swimsuits with sport cuts — racerback, high neck, or cross-back — designed to accommodate broader shoulders and a narrower waist.

Most one-pieces off the rack assume an hourglass shape. If you have a V-taper (wide shoulders, narrower hips), standard straps will slide off or dig in. Racerback styles pull the straps toward your spine, so they stay put. High-neck or mock-turtle styles also help balance a broad chest.

Fabric matters too. Look for compression or high-stretch blends (nylon/spandex, polyester/PBT). These hold their shape and won’t sag after a few laps. Brands like Speedo, TYR, and Jolyn are built for this. Avoid thin, ruching-heavy suits — they’ll bunch up and offer zero support.

If you want something less competitive-looking, try a crossover back or a cutout one-piece that still has wide straps. And skip anything with shelf bras — they’re useless for active use.

A swimsuit that fits right should feel like a second skin, not a cage.
