Ahh, do you feel that? That's the sensation of warmth touching your skin, the smell of charred BBQ filling your nostrils, the sound of the ice cream truck coming down your block—that's summer coming! And I'm so ready to hit the beach, pool, and whatever island that beckons my name. So what's a girl to do to best prepare? Swimsuit shopping, ofc! TBH, I've got mine done a long time ago (ahem, winter shopping) but may I suggest a one-piece or two to add to your summer arsenal?
I get how frustrating swimsuit shopping can be especially when you don't know which style would best complement small busts (these will actually stay in place) or big busts (these will provide more support than your typical bikini) but I'm here to make life a lil easier for ya with a rainbow assortment of options. We're talking low-back swimsuits if you're feelin' spicy and chill designs so there's a fierce slay for every comfort level, some retro vibes, highly-reviewed Amazon choices, the latest drops from the brands blowing up your Instagram feed, and so much more. Truly, whoever said one-pieces are boring, clearly has never seen my picks. In this list, you'll discover some versatile and fun styles you won't be able to resist.
Our top picks for the best one-piece swimsuits in 2024:

Rave Review: "I normally don’t write reviews but this. suit. is. perfect. (Full disclosure, I haven’t used it, just tried it on but) I am sooo happy with the fit. And it feels great quality and like it will hold up well with use. I am 6 ft tall with short legs—yes I am 99% torso. I have tried so many companies “long/tall” bathing suits and none have hit the mark. This is the first suit that fits. Didn’t think I’d have confidence in my postpartum beach body for a longggg time but this suit makes me feel amazing."
