What is the bra size 34DD? What exactly is the bra size 34DD? First, it’s a combination of a band size and a cup size. The 34 refers to the band and the double D (or “DD”) refers to the cup size.Read more...
The cup size DD can also be called an E cup size in European brands, so a 34DD in U.S. sizing would be a 34E in European brands like Chantelle and Prima Donna bras. This can be confusing for women when trying to find their 34DD cup size in a European brand. But, problem solved! HerRoom has the solution with our exclusive Universal Cup sizing™ (UCS®). Cup sizes DD and E combined are equal to a UCS® D2 size. So, all you need to do is search 34D2 at HerRoom and you’ll find all the bras, swimwear, shapewear and more that come in your size.
Every bra size has a set of sister sizes. These are bra sizes where either the band, cup or both are just one size up or down from 34DD. For examples a 34DD or 34E bra size has sister sizes of 32DDD (D3) and 36D. So, these three bra sizes – 32DDD, 34DD, and 36D all represent bras with the same cup size (when you go up a band size, you need to go down a cup size to maintain your cup volume) but different band sizes. A 32DDD has a smaller band than a 34DD, and a 36D has a larger band than a 34DD bra size. IF a 34DD and 34E bra size fits you, this generally means your under bust measurement is 29 to 31 inches, and your over bust measurement is 38 to 39 inches.
Bra size 34DD is 75DD in Europe and Japan, 90DD in France, and 12DD in Australia.
