24 Best One-Piece Swimsuits for Every Body Type

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.

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.”

Best for Large Busts

If you have a D-plus cup size, chances are you want more structure than a basic wireless one-piece can offer. The best swimsuits for large busts tend to have features like thick adjustable straps, underwire cups, and extended sizing that help breasts feel more secure and supported. Among the standouts we tested: TA3’s buzzy Plungey suit, which has a lace-up back that lets you customize the fit through the bust and accommodates up to H cups, and the Miraclesuit Escape, which pairs underwire support with padded straps that feel noticeably more comfortable on the shoulders.

Best for Small Busts

On the other end of the spectrum are swimsuits for small boobs, which focus more on creating shape and enhancing the bust. Pepper designs bras and swimwear for smaller cup sizes, including AA cups, and its Lift Up one-piece has subtle push-up padding that gives extra lift without gaping. We also liked plunging cuts from J.Crew and Cupshe, which draw attention to the bust, along with sporty scoop and racerback silhouettes that pull the bust in and up.

Best Plus-Size

Many popular swimsuit brands cap their sizing at XL or aren’t designed with curves in mind. The best plus-size swimsuits use details like supportive bust construction, compressive fabric that minimizes bouncing, and sizing that extends beyond 3X. Among our favorites are Shapellx’s sculpting plunge suit, which offers strong tummy control, and Old Navy’s halter one-piece, whose adjustable neckline lets you customize your level of chest coverage.

Best High-Leg

High-leg swimsuits are having a moment, channeling Pamela Anderson à la Baywatch, with leg openings that rise above the hips to create the appearance of longer legs. The silhouette is unabashedly sexy and often paired with the dramatic plunging necklines and a cheeky fit in the back. One of our favorites is Free People’s Free-est Amber one-piece, which is in turn low-cut (in the front) and high-cut (in the back) and comes in many patterns and colors.

Best Full-Coverage

Of course, sometimes you want a swimsuit that keeps you fully covered in the back, whether you’re swimming laps, strolling, or stretching out for a nap. Summersalt and Andie make some great fuller-coverage one-pieces, including the Sidestroke and Malibu, the latter of which has adjustable snap buttons at the neckline. Swim dresses are another solid option if you want even more coverage across the bikini area, while still feeling polished and feminine.
