Now that the weather has gone from “perfectly pleasant summer” temps to step-outside-and-sweat-through-your-entire-shirt season, wearing actual clothing feels increasingly optional. Unless there’s a strict “no shoes, no shirt, no service” policy in place, I’ll be treating my bikini collection like everyday attire.

If you’re on the same wavelength (it’s purely a survival tactic at this point), consider this your official sign to add a few new swim styles to your cart. Trust me, you’ll need ’em—and Amazon’s cutest suits are conveniently getting the Amazon Prime Day treatment right now. Fair warning: The sale ends tonight, so there’s no time to waste! Go check out the chicest styles your shopping fairies have rounded up—they look far more expensive than they actually are.

P.S. Amazon Prime Day is live now through Friday, June 26!

Think: swimwear deals on the season’s hottest polka dot prints, charm details, timeless triangle bikinis, and sleek bandeaus. Oh, and did we mention our favorite finds start at just $15 for a full set? Yep, that’s what sold me, too.

Yes, your eyes aren’t deceiving you—tankinis are having a major moment right now, and honestly, I’m here for the nostalgia. After finding this gorgeous teal set, I’m officially on board.

I’m obsessed with the details on this one-piece that make its simple silhouette feel so much more special. The ruffled sleeves! The ruching! The deep V neckline! And the pretty mauve color is everything.
