At long last, it’s swimsuit season. With sunny weather for the next couple of months (remember: summer’s finale isn’t til September 23), it’s worth a gander at your wardrobe to take inventory of your swim staples and fill in the gaps. Cover-up? Check. Straw hat? Check. Flip flops? Check. On the swimwear front, the best one-piece swimsuits are always a wise investment—and can be even more fun than a bikini.
The season’s assortment of one-pieces feels varied and fresh, with unique necklines and design details in abundance. On the one hand, you have options from perennial favorites such as Eres and Melissa Odabash, who reliably offer a sleek, minimalist take on swimwear. On the other, designers like Johanna Ortiz and Lisa Marie Fernandez continue to evolve the category with fanciful embellishments, including ruffles and belted silhouettes. For every timeless color and cut, there’s a one-piece in a riveting pattern or saturated hue. In essence, there’s a world of choice when it comes to the best one-piece swimsuits. Ahead, our edit of 56 options that make a splash.
The Little Black Bathing Suit
A classic black swimsuit—both bikini and one-piece—will always feel right. But to keep things interesting, opt for unique necklines, shoulder silhouettes, and design details like cut-outs and scalloped edges to differentiate the look.
The Always in Style, Classic Suit
Everyone should have a failproof, classic one-piece that can be tossed on at a moment’s notice. Look for silhouettes that make you feel most confident (a classic rounded neckline, perhaps?) and a color that can complement your summer separates.
The Smocked Fabric Suit
Crinkled, smocked fabrics give texture and depth to a swimsuit. Crafted in rainbow brights and neutrals alike, the season’s best one-piece options come in a slew of silhouettes, from a contemporary asymmetrical shoulder shape to classic halters and spaghetti straps.
The One-Shouldered Suit
Asymmetrical shoulder shapes are made uniquely interesting this season with unexpected design details like doubled straps and unique cutouts. Wear yours with an oversized white linen blouse by the pool.
The Nautical Suit
A nautical theme feels destined for a summer day spent in the sand, and the season’s swimsuit picks all feel fresh and versatile. Lean into the aesthetic with a blue and white stripe suit and look for playful details like lace-up ties and gold hardware.
The Not Too Sweet Floral Suit
A natural choice for the warmer months, floral swimsuits are a reliably stylish choice for your time spent in the sun. You’ll have your choice from micro florals that nod to the ’90s as well as larger patterns that lend a graphic quality to the one-piece.
The Halter Neck Suit
A classic silhouette with a consistently flattering effect, the halter is a forever pick. Go for a scalloped option from Marysia or slip into a neutral-hued one-piece from Eres for a timeless take.
The Waist-Cinching Belted Suit
Textural swimsuit straps, belts, and ties all add a three-dimensional element to one-pieces this summer. Look for these details if you’re the kind who leans toward statement-making swim.
The Vacation-Ready Suit
Heading OOO? You should dress the part. Whether it’s a far-flung holiday in the Mediterranean or a weekend escape to the sea, the season’s most celebratory one-pieces come in loud colors and playful prints (Gucci’s boat print is a particular favorite).
The Trendy Cut Out Suit
When placed strategically, cutouts can transform a one-piece swimsuit. Go for a strapless suit with a splice in the center or pick a one-piece with a larger cutout in the center for a flattering effect.
The Micro Detail Suit
Even if you’re not one for strong colors and prints, there’s still a way to make your one-piece stand out. Swimsuits with micro details such as laser cutouts and broderie anglaise can add a perfect finishing touch.
The ’70s Print Suit
Psychedelic patterns and retro wallpaper florals make their way onto swimsuits this season. Add a hint of nostalgia to your summer swim with a one-piece that feels reminiscent of stylish times past.
The Retro Glamor Underwire Suit
For those with a fuller chest, finding a supportive swimsuit is a common quest. Underwire is an easy solution that acts like a bra but blends in with a poolside ensemble.
The Sporty Suit
Athletic silhouettes meet movement-inducing design details like neoprene fabrics, utility zippers, and neutral colors. The best sporty swimsuits are ideal for a long, leisurely swim in the ocean.
