19 One-Piece Swimsuits You'll Be Thrilled to Ditch Your Bikini For

It's all about the plunging necklines and cheeky cutouts.

Kat Irlin

Maybe there was a time when one-piece swimsuits were seen as dowdy or matronly...but, honestly, we can't remember it. One-pieces are essentially the bikini's more flattering counterpart (seriously, they somehow look good on everyone). After seeing the latest trendy cutouts, graphic patterns, and strappy details, you'll forget why you ever wanted a two-piece in the first place. Take a look at the best one-pieces ahead of your tropical getaway—and if you're not going anywhere? Invest in one now, and have something to look forward to for summer.

Best Denim One-Piece
Louise Cutout Denim Swimsuit
Karla Colletto modaoperandi.com

Blue jeans fans rejoice, I found a cute denim swimsuit. You'll quickly count this as one of your favorites because of the plunging neckline and and cutouts with a sexy front tie fastening. Just like your favorite denim bottoms, this one looks cute with anything, like that cotton maxi skirt in your closet.

Best Sheer One-Piece
Strapless Parrot Swimsuit
Cult Gaia x Adriana Degreas adrianadegreas.com

Channel the nature vibes of Brazil in this macaw appliqué swimsuit. The one-piece features a mesh middle so the design looks imprinted on your skin while the strapless style helps you avoid shoulder tan lines. This piece is a must-have for summer and will make a statement at the pool or on your 'gram.

Best Shirred One-Piece
Burgundy Shirred Ring Swimsuit
Topshop topshop.com

This affordable swimsuit has cutouts all over and a ring detail on the straps for that not-too-simple look. You'll notice the one piece isn't completely smooth either because it's made with a shirred material. Trade in your black swimsuit STAT for this baby.

Best Peplum One-Piece
Gramercy One-Piece Swimsuit
Marysia Swim modaoperandi.com

Keep your one-piece swimsuit playful with a peplum waist and gingham print. This one from Marysia comes with a fun little black dotted trim. A plunging neckline and equally low back adds allure to the otherwise super sweet look.

Best Long-Sleeve One-Piece
Mira Printed One-Piece Swimsuit
Verandah modaoperandi.com

One thing I love about long-sleeve swimsuits: you can go easy on the sunblock. This is perfect for those who are looking for fuller coverage, but still want something fresh and eye-catching. (Peep the adorable floral print.) Add a straw tote or sunglasses and you're good to go.

Best Printed One-Piece
Nativa Ruffled Printed Swimsuit
Agua by Agua Bendita net-a-porter.com

Sorry, what were you saying? I was lost in a daydream about all the places I could wear this swimsuit to, from the beaches of Costa Rica to the shores of Fire Island, New York. The palm tree print is so vibrant, I can almost smell the ocean and taste the dollar coconuts. You already know this is on my wishlist.

Best Convertible Strap One-Piece
Shaping Swimsuit
H&M hm.com

A ruched bodice gives this fully lined swimsuit a sculpting effect on the tummy, back, and butt. Aside from the flattering silhouette, you can wear this one piece with or without straps, if you want to avoid tan lines. For just $35, this floral swimsuit is a steal.

Best Two-Toned One-Piece
Black and Beige One-Piece Swimsuit
House of Harlow 1960 x Revolve

Not ready to leave the comfort zone of black swimsuits? Ease yourself into "colors" with this half-beige, half-black one-piece. Though the hues are tame, the swimsuit itself has a low-cut front and back for a sultry look. Wear with shorts and beige sandals to dinner—it effectively becomes a bodysuit.

Best Strapless One-Piece
Striped One-Piece Swimsuit
Cami and Jax

A swimsuit that throws it back to your favorite tube tops of yesteryear. Unlike those ones, however, this one piece won't slide around—it'll stay right where it is, thanks to the side boning on top. Plus, laces in the back give you the option to wear this swim piece looser or tighter, depending on your preference.

Best Polka Dot One-Piece
The Nina Polka Dot Swimsuit
Solid & Striped

Take the guesswork out of which accessories to pair with your swimsuit. This option from Solid & Striped comes with a white belt to match the polka dots. With just this one small tweak, the vintage-style swimsuit becomes way more interesting. Style with white cat-eye sunglasses and a floppy hat.

Best Halterneck One-Piece
Lynn One Piece With Sash

I'm not sure what to focus on first—the black sash, the side cutouts, or the back of the swimsuit. There's a lot going on here, but the designs come together in a harmonious way that makes the-one piece extra special. If you're looking for something a little different, this is it.

Best Pink One-Piece
Posy One Piece

This swimsuit looks so sweet, it makes my teeth hurt. (You can thank the baby-pink floral print and shoulder bows for that.) As "covered up" as this one-piece may seem, the back does dip pretty low—though not so low you need to worry about exposing anything.

Best Mesh Paneling One-Piece
Leopard Print Swimsuit
Norma Kamali

Anyone can design a leopard print swimsuit, but Norma Kamali takes it one step further with mesh paneling. This one-piece gives the illusion of skin-baring cutouts and looks sexy without appearing tacky; meanwhile, the high-cut sides elongate your legs. Just make sure to apply sunscreen evenly, so you don't get a one-shoulder strap tan line.

Best Cutout One-Piece
Floral & Polka Dot One-Piece Swimsuit

Australian label Zimmermann is famous for its romantic resort wear in floral patterns, and it's beloved by celebrities like Kendall Jenner, Chrissy Teigen, and Margot Robbie. If you want to dress like the stars do, invest (I say this because it's a little pricey) in this airy cutout swimsuit. You won't regret it once the compliments start rolling in.

Best Sporty One-Piece
Lipsi One-Piece Swimsuit
Tory Burch shopbop.com

When I want a little lift in the chest area, I turn to bustier-style swimsuits. This sporty two-toned one-piece from Tory Burch falls right into that wheelhouse. It has molded underwire cups, a pretty waistband, and adjustable straps. I couldn't ask for more.

Best Scalloped One-Piece
Scallop Bandeau One-Piece Swimsuit

Scallop detailing is a cute way to add detail to a black swimsuit without resorting to crazy ruffles or cutouts. This strapless piece has just a tiny cutout in the middle to bring out the scallop detailing, but is otherwise a no-fuss design you can wear to the pool or on a sun lounger.

Best Simple One-Piece
Black One-Piece Swimsuit
Bromelia Swimwear

Made in Brazil, this black one-piece has amazing stretch so it doesn't sit too tight across your figure. The delicate straps turn into a racerback style from behind, and a cheeky fit reveals just enough of your butt without your feeling totally embarrassed about it.

Best Shaping One-Piece
Polka Dot One-Piece Swimsuit

Let's go back, back to the '60s with this polka dot halter. You can't tell from this photo, but it even has an underwire to support larger busts, while the triple-strength spandex smoothes your figure. Ready to get your retro vibes on?

Best Mommy and Me One-Piece
Black and White Striped Swimsuit

This matching two-piece set is perfect if you're a mom who wants to match your little one. It's also a great gift for your cousin or niece because, obviously, she wants to be just like you. You're not a regular aunt, you're a cool aunt.
