Size 40C Swimwear

Find 40C swimwear designed for a more accurate bust and band fit than standard swim sizing. In this size, sizing up for cup room can leave the body loose, while sizing down can make the cups feel shallow or tight. Bra-sized swimwear helps reduce that tradeoff. Browse 40C bikinis if you want a two-piece fit, or use our swimwear size chart to compare your best starting point before choosing.
