Whether you’re lounging poolside, spiking a beach volleyball, or heading into the waves, the best one-piece swimsuits let you move comfortably without constantly adjusting your suit. The right style depends both on how you plan to wear it and the kind of fit you’re after—maybe that’s light stomach smoothing, extra bust support, fuller coverage, or a trendier high-leg silhouette. To find the standouts, Glamour’s shopping team tested bestselling styles from top swimwear brands, evaluating them for fit, feel, and (of course) looks. Below, shop our favorite one-piece bathing suits for every preference and body type.
Our top one-piece swimsuits for summer 2026
Best for Tummy Control
Like shapewear, tummy-control swimsuits are designed with compressive fabrics, ruching, and shirring that smooth and stabilize the midsection—support that can feel especially good on days heavy with motion. Glamour commerce editor Malia Griggs tested a dozen swimsuits to find ones that offered the best shaping. Among her favorites: The viral Andie Amalfi, a classic black one-piece with light compression that “functions almost like a bodysuit,” she says. Another top pick was Summersalt’s Perfect Wrap. “This was one of the most flattering suits I tried,” she says. “It has an extra wrap layer you cinch at the waist, which draws attention away from the stomach. The compression is quite snug, smoothing, and comfortable.”
