Size 40D Swimwear

Shop 40D swimwear made for a fuller cup fit on a 40 band, without relying on broad swim sizes that can feel too loose in the body or too shallow in the bust. Bra-sized swimwear helps you start closer to your real fit, especially when you want better containment through the cups. Explore 40D bikinis for two-piece options, or check our swimwear size chart if you want to compare sizing before you choose.
