The 17 Hottest Swimsuits of the Year, From Cutouts to Plunging Necklines

Moonslover One-Shoulder High-Waisted Bikini ($31)

We'd argue that the sexiest bikinis are high-waisted ones because the styles always prove to be both cute and flattering. If you're in the market for a classic high-waisted bikini, opt for a stretchy and fun choice like this colorblock piece from Amazon. We adore the fun orange shade because it feels so fresh and fun for spring.

Ashley Graham x Swimsuits For All A-List Plunge One Piece Swimsuit ($24-$134)

If you want something timeless and flattering, you really can't go wrong with a sexy one-piece. With its plunging neckline, tie accents on the hip, and thicker straps (which help to provide ample support), this sexy bathing suit checks all of our boxes and is undeniably stylish, too.

Qinsen Halter Thong Bikini Set ($30)

As far as sexy one-pieces go, this skin-baring style is definitely one of our favorites because of its hot-pink coloring (perfect for embracing the Barbiecore trend) and playful cutout detailing. We love the timeless halter style mixed with a more modern silhouette. Not only is this one of the best one-piece bathing suits, but it can even double as a stylish bodysuit with denim shorts.

Montce Swim Lilac Sparkle Brasil Bikini Top ($58, originally $88) and Montce Swim Lilac Sparkle Brasil Bikini Bottoms ($67, originally $88)

We've never seen a silhouette quite like this, so it's bound to upgrade your swimsuit drawer with flair. From the clever cutouts and strappy accents to the darling purple coloring, this sexy bikini combines so many different trends into one playful style. Plus, the pairing of the halter top and double string bottom is sure to help you make a splash, whether you're poolside or swimming in the ocean.

Summersalt Perfect Wrap One-Piece ($95)

The shape of this suit isn't just eye-catching, it's figure-defining, too. We adore the two-tone look, and with the swimwear being available to shop in three other shades and patterns, the style definitely lands at the top of our list for being one of the best one-piece bathing suits. If you're looking for a suit that is sexy but still has full coverage, this is a great choice.

Andie Swim Malibu One Piece ($98)

Whoever said an athletic bathing suit can't be sexy clearly hasn't seen this one. You'll feel like your best self in this style and, perhaps best of all, will still feel comfortable doing all of the water activities you love. This sexy one-piece comes in lots of cute colors, but the red is such a timeless choice. We also love that you can choose a classic fit or a fit made for someone with a long torso.

Montce Swim Jade Floral Dainty Bikini Top ($89, originally $132) and Montce Swim Tie-Up Bikini Bottom ($26, originally $82)

Stick to the classics, and opt for a floral bikini like this flattering style from Montce. This is one of the sexiest bikinis for summer because it features a subtle floral pattern throughout, and we love the pairing of the supportive underwire top and sexy string bottom.

Andie Swim Mykonos One Piece ($118)

This flattering and sexy one-piece swimsuit is supportive and flirty, which can be tough to find if you have a larger chest. The thick under-band will help keep everything together, while the plunging neckline will allow you to make a statement in any season. Plus, this is one of the best sexy bathing suits because of its versatility. If you don't want to strictly wear it as a swimsuit, the piece also looks good paired with comfortable pants or a sarong.

Jade Swim Micro Strap Muse Scoop Top ($118) and Jade Swim Micro Bare Minimum Bottom ($118)

This suit — available in black, white, or nude — is for the minimalist who loves a skimpy bottom with floss-thin straps. While the top doesn't plunge and is rather standard, it does allow you to put your cleavage on display with its scoop neck cut. The bungee-cord straps are also stretchy enough to feel comfortable while lying flat on your skin.

Belle The Label The Oracle Bikini Top ($144) and Belle The Label The Bare Bikini Bottoms ($78)

If you've got a larger chest or you're just someone who prefers a little extra support up top, an underwire bikini top is such an essential. This skin-baring bikini is equally supportive and sexy, with thick straps that help to keep everything in place and a balconette-style silhouette that hugs the body in all the right places. The sexy bikini bottom is also great because it rides the line between a cheeky cut and a thong cut, making it the ultimate minimal sexy swimsuit.

Beach Riot Celine Shine One-Piece ($148)

A bit of sparkle is never a bad idea, which is probably why we love the look of this cutout one-piece so much. The side slits on this sexy bathing suit will definitely turn heads, and they'll also help to promote airflow and create a more breathable fit. The style comes in several pretty shades, but we like the green coloring the best.

Riot Swim Echo One-Piece ($150)

If you've yet to stock up on one of Riot Swim's many sexy one-pieces, you're seriously missing out. This particular style is one of the most popular pieces on Instagram and TikTok at the moment, and we can't get enough of its plunging neckline, high-cut sides, and ruched, figure-flattering middle. It comes in a ton of fun shades, so it'll be hard to pick just one.

Lisa Maree Check Me in Crochet String Bikini in Gold ($165)

This bikini, which gives off a nude effect in the sunlight, has ties at the hips, neck, and back, so you can manipulate it to sit exactly where you want it to. While you might've avoided crochet fabric before, it's easy enough to clean (just throw it in the wash on a gentle, cold cycle and lay it flat to dry). The bottoms are cheeky and the triangle-shaped top barely covers the nipple, making this skimpy set a bold move at the beach.

Montce Swim Cream Rib Tropez Tie-Up One-Piece ($198)

Leave little to the imagination in this sexy bathing suit. The tie-up accent on the side is both playful and practical, allowing you to adjust the piece to achieve your perfect fit. Besides the eye-catching silhouette — with a deep plunging accent as the centerpiece of it all — this cute one-piece is great because it comes in a few different colors and boasts a universally flattering fit. We especially love the cream hue.

Solid & Striped The Bella Butterluxe Blackout ($198)

This strapless swimsuit is undeniably sexy and chic at the same time, and it's the very look of the quiet luxury trend that's taking hold of the fashion world. With a completely open back, waist-defining cutouts, and flattering white piping, you can trust the compliments to pour in.

Mikoh Clara One-Piece ($234)

This swimsuit has so many stomach-revealing cutouts, it might as well be a bikini. It's also got a minimal-coverage bottom, and you can either tie the top-most strap as a bandeau or around the neck like a halter. The options for versatility are endless, which means a different sultry look each time you wear it.

Camilla Ring Detail Plunge V One-Piece in Dear Amore Mio ($379)

This new arrival from Camilla is eye-catching in all the right ways. Splashed with a feline motif and featuring a ring detail above the abs that makes the number even more skin-revealing, the plunging one-piece will capture anyone's attention. Team it with the matching sarong and slides for a full circle moment.
