Most Supportive Swimsuit for Large Busts: Cuup The Scoop Swim Top
Our editors are obsessed with Cuup’s silky, supportive bras—so it’s no surprise that we’re on board for the brand’s swimwear. Glamour commerce writer Andrea Navarro previously called The Scoop bra (which this bikini top based on) one of the most comfortable bras she’s ever tried. “It’s next-level soft and doesn’t make me feel like I can’t breathe even if it’s on for hours. I love that the bra’s straps are wide-set. As for support, it’s as comfy as it gets for a wire bra,” she says. Pair it with Cuup’s matching high-waist bottoms for retro pin-up girl vibes. And if The Scoop isn’t your style, you’ll find balconette, bandeau, string, and plunging necklines too.

Best Plus-Size Swimsuit for Large Busts: TA3 Squarey One-Piece
“I have very large breasts (am currently a size 36 F or G, for context) and never felt secure in any swimsuit I tried on unless I looked like I was going scuba-diving with a team of grandmother nuns—meaning that only the least-cute options are what provided actual support. That’s until I found TA3’s suit!” Glamour associate beauty editor Danielle Sinay says of this suit, which is designed with a corset-style back that’s as slyly supportive as it is, well, hot. “It essentially functions as gorgeous shapewear with a built-in bra. Ever since getting mine (which I now have in several colors), I actually feel comfortable going to—and running on—the beach!”

Best Splurge Swimsuit for Large Busts: Form and Fold D-G The Crop Recycled Bikini Top

Plus, I can adjust the wider straps as I see fit.” That “lift” is thanks to hidden underwire that provides structure without that rigid look. For the total package, add Form and Fold’s high-waist bikini bottoms to cart.
