15 One-Piece Swimsuits You Need on Your Radar

You know who is good at making swimwear? Lingerie designers. They just get it, don't they? Exhibit A: Morgan Lane's collection of suits, which are equal parts sexy and flattering. 

Do you ever think to yourself, "how can I accomplish street style success on the beach?" Alberta Ferretti has answered your questions by turning her ubiquitous days of the week sweaters into beautiful Instagram-worthy bathing suits. 

Oh, Stella McCartney. How I love thee? Let me count the ways. Your brand is eco-friendly, chic, and makes one-piece bathing suits. 

A bathing suit with an underwear and corset-like bodice may just be the sexiest one-piece we have seen yet. And in this color? Perfection. 

Brazilians look the best in bathing suits, so it's only fitting that they'd make great ones, too. Enter: Lyggia & Nanny, creator of this amazing color-blocked masterpiece with a removable/adjustable strap. 

Is there anything Tory Burch can't do? Seriously. Work wear, date night outfits, the best accessories, chic stuff to wear to the gym, and an eyelet white bathing suit? 

The color. The peplum. The bathing suit dream.

Are you a minimalist that wants to try out "sexy"? Jade Swim is for you. Calm and serene in the front and WOWZA in the back, and in the perfect shade of brown, this suit has it all. Oh, and it's under $200. You're welcome. 

Has there ever been a better name for a bathing suit line than "On The Island?" If that's not reason enough to invest in one of these suits...get it for its fun, handpainted prints and ridiculously flattering cuts. 

LMF's "Jasmine" zip up suit is not a new style, but it's a tried and true style, and one the bathing suit designer (beloved by celebs and fashion influencers alike) keeps updating it in fun patterns and prints like this polka-dotted style. 

CAUTION: Norma Kamali's swimsuits are not for the shy beach-goer. If your poolside style icons include Kourtney Kardashian, Chrissy Teigen, or Nikki Minaj, this onesie's for you. 

Do dreams come true? Ganni made a capsule of beachwear so, um, yes, dreams do come true. 

One-piece does not equate to "covered-up." See here for Haight's Band Tie-Waist swimsuit, which is, like, J.Lo Versace Grammys gown sexy. 

Initially, Solid and Striped was a fashion editor favorite for the brand's simplicity: they just made great, basic suits. But the swimwear line's latest collection proves they are so much more than a boring black one-piece. Case in point: This ribbed belted one-piece in the chicest tri-color combo ever. 

We love Caroline Constas' ready-to-wear collections for their vibrancy. It's as though the dresses and tops dance when you wear them. So it's no surprise we'd be addicted to her swimwear collection, too.
