The Best One-Piece Swimsuits for Summer

For Watersports, Surfing, Lounging, and Beyond—No Bikinis Required

In December, we shared our favorite bikinis of the season. And while we love the tan-line allure of a triangle two-piece, a one-piece swimsuit can offer greater security for an active day on the water. Thanks to the creativity and originality of some of our favorite brands, there are fabulous one-piece swimsuits for every type of person and style. Here’s a curated collection of the swimsuits guaranteed to make a splash on your next ride.

Hunza G pink square neck one-piece swimsuit

I am not shy about my love for Hunza G. While these suits receive praise for their one-size fit, the details of the suits cannot be overlooked: the cuts are timeless, the crinkled fabric adds sui generis texture. My favorite part? Their collections always show-off bold, eye-catching colors. For a contemporary take on a classic shape, the Square Neck Swim is a must-have staple.

Onia Allegra blue gingham one-piece swimsuit

I purchased my first Onia suit back in December to bring on a sailing trip in Thailand and carry no buyer’s remorse. All of their swimwear has a clean trim that makes the fashionable styles feel more secure and sleek. The blue gingham on the Allegra One Piece is subtle enough that it is rewearable, compared to statement pieces that sometimes can feel overdone when reworn frequently. The ruching around the midsection guarantees a flattered figure as well.

Monday Swimwear geometric print one-piece swimsuit

Monday Swimwear refines style rather than chasing trends. The Los Angeles-based brand’s collections aim to instill confidence and flatter the female form. I recently wore their Montego Mini Dress as a cover-up on a tropical getaway and was astonished by just how flattering it fit!

Marie Oliver printed one-piece swimsuit with belt

For swimwear that simultaneously channels “Euro Summer” and Southern charm, look no further than Marie Oliver. Founded in Greensboro, North Carolina, the brand leans into the South’s affinity for color and print, delivering pieces that are joyful and polished. I, for one, have been eyeing the Attina One Piece as the suit of the spring. The belt, the custom print, the silhouettes, the colors—it has it all.

Lido red bandeau one-piece swimsuit

Show off your décolletage in this fire-engine red Lido swimsuit. A strapless one-piece can strike that elusive balance between nonchalance and intention. In the spirit of packing light but dressing well, the suit moonlights rather brilliantly as a top. Throw on some linen trousers and you’re suddenly dinner-ready, the transition from poolside to aperitivo handled with maximal efficiency.

Boden blue floral halter one-piece swimsuit

Named after the Greek island, Kythiura, said to be the birthplace of Goddess Aphrodite, this ruched, tie-neck swimsuit from Boden has me in love and craving a European getaway. The suit also comes in a variety of fit options and colorways. Being on the taller side, my biggest gripe with one-pieces is that many are too short for my torso. Boden, always thinking about quality and style, ingeniously offers a long-torso version for its tall customers in addition to petite and standard sizing.

Staud Maeve striped bustier one-piece swimsuit

Staud’s Maeve One Piece in Montauk Stripe is delightfully nostalgic—like a sun-faded postcard or the first bite of a watermelon on a too-hot afternoon. Designed as a nod to the classic bustier, the suit’s summery colors feel lifted from a lineup of popsicles. What’s more is the straps are mercifully removable: wear the swimsuit when skimming across the water atop a jetski or lose them entirely when the mood calls for something a bit more languid.

Dos Gardenias neoprene one-piece swimsuit

As a San Francisco native, I feel compelled to remind everyone that just because the sunny season is back, does not mean all bodies of water follow suit in temperature. For those braving brisk waves, or simply eager for a bit of extra insulation, Dos Gardenias’ Rose One Piece offers wet-suit thermal regulation in an unassuming style. The silhouette is clean and features a modest scoop neck, a deeper scoop back, and high-cute legs that subtly elongate the frame. It’s functional, certainly, and is exactly the sort of piece you’ll be grateful for long after the initial plunge.

Alice and Olivia x PQ Swim scroll motif one-piece swimsuit

In case you missed our recent spotlight on the fabulous Alice & Olivia x PQ Swim collaboration, it’s worth a second look. This elevated halterneck style, adorned with striking scroll motifs beckons class. The subtle peakbook slit at the front combined with the slightly cheeky cut in the back offers just the right touch of flirtation.

Jade Swim Ella black cutout one-piece swimsuit

In Jade Swim’s Ella One-Piece, the ringed cutouts lend intrigue, transforming any otherwise classic style into a jaw-dropping summer staple. As much as I am a color fanatic, I also feel that everyone should own a black swimsuit. They are unfailingly sleek, endlessly versatile, and, in this case, a fashion statement ready to be made.
