Bust Support at the Beach: One-Piece Swimsuits with Underwire

Swimwear and lingerie share a lot in common. Yet it can often feel like support and shaping concerns are thrown out the window when lace gets replaced by swim fabrics. Well, not so much with bikinis, with bra top styles easy to find. But want a one-piece? Then prepare to sift through an endless array of wire-free swimsuits before you find one designed for support.

Sure, plenty of people enjoy being free of all that bust scaffolding for once. But for others, worrying about falling out of your swimsuit can suck all the fun out of being in the water.

For once, it seems it’s easier to find something made for DD+ than in A-D sizes. Full-bust brands are, naturally, more likely to consider support. But you don’t need to wear a large cup size to crave the lift, and round shape underwire can offer.

Below are 15 swimsuits with underwire to check out, whether you wear an A cup or an I cup. Some feature obvious, bra-style cup, for those who like that silhouette and separation. Others have the wires hidden away inside, for a sleek outer appearance that mimics their non-wired counterparts. Whatever your size, tastes or budget, you can look stylish and feel secure at the beach!
