30DD Bras, Lingerie, and Swimwear | 30DD Bra Size

Bra sizing can be confusing, especially with different international standards. 30DD lingerie and swimwear in US sizing is equivalent to a 30E in European brands like Chantelle, Empreinte, and Prima Donna. That’s why HerRoom created the Universal Cup Sizing™ (UCS) system, which helps you shop across different brands with ease. By searching for 30D2, you’ll find all the bras and swimwear that match your size, whether the label says DD or E.
