Bra-sized swim tops are the move.

Skip anything labeled S/M/L and look for cup sizes (like 38DD or 42F) from brands that know bras. Regular swimsuit sizing is a gamble for large busts – you either get a tent on top or a nip slip waiting to happen.

Underwire or soft-cup construction gives actual support. Wide straps help, too. Halter tops can work if the neckline is sturdy enough, but most just dig into your shoulders after an hour. Tankinis with built-in underwire are solid if you want more coverage, and high-waisted bottoms balance out a bigger chest visually.

Don’t waste money on cheap shelf-bra suits. Your girls deserve better than a flimsy triangle.
