Size 40DD Swimwear

Shop 40DD swimwear for a more precise fit through the bust, band, and body. In this size, standard swim sizing can create a frustrating tradeoff: enough room in the bust may mean a looser overall fit, while a better body fit may leave the cups too shallow. Bra-sized swimwear helps narrow that gap. Browse 40DD bikinis for two-piece styles, or use our swimwear size chart to check your best starting size.
