D cup is where bra-sized swimwear starts to earn its place. Even at D cup, a swim top built with a proper underwire and structured cups holds its shape in the water and supports through a full day — where a stretch triangle simply flattens and rides up.
What to look for at D cup
Underwired or moulded cups, adjustable straps, and a band that sits level and firm on the ribcage.
Brands and styles
Freya Swim, Panache Swim and Fantasie Swim all range D cup well across bikinis, one-pieces and tankinis. Browse the full swimwear range or see D cup bras for everyday styles.
