At DD cup, swimwear needs real structure. A swim top that relies on stretch alone won't hold a DD cup bust in the water or through a day at the beach — the cup needs an underwire and firm fabric to lift and contain, the same way a well-fitted bra does.

Getting the fit right at DD cup

Prioritise underwired or moulded styles with adjustable straps and side support. Because everything here is bra-sized, you buy your swimwear in your bra size — no guessing between S/M/L — and the cup is shaped for projection rather than just draped over the bust.

Brands and styles

Freya Swim, Panache Swim, Fantasie Swim and Elomi Swim all cover DD cup across bikini tops, one-pieces and tankinis. See DD cup bras for everyday styles. Sizes 6 to 20.
