What is the bra size 34D? If this is your bra size, your band size is 34 and your breast volume fills out a D cup. You are also lucky, because most bras on the market are made in your size. Read more...
Some women cringe to think they are a D cup size because they think a D cup size is really big. Well, it’s not in this band size.
What are the sister sizes to a 34D bra size? There are several. 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 34D. For example, a 34D bra size has sister sizes of 32DD and 36C. These three bra sizes – 32DD, 34D and 36C – 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 32DD will have a smaller band than a 34D, and a 36C will have a larger band than a 34D. A 34D bra size generally means your under bust measurement is 29 to 30 inches and your over bust measurement at its fullest point is 37 to 38 inches.
Note about the sister cup size 32DD: The cup size DD can also be called an E cup size in European brands, so a 32DD in U.S. sizing would be a 32E in Chantelle and Prima Donna bras. This can be confusing for women when trying to find their 32DD cup size in a European brand. I’ve recognized this problem – thus, HerRoom has made finding your true size simple with our exclusive Universal Cup Sizing™ (UCS®) system. 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.
Bra size 34D is 75D in Europe and Japan, 90D in France, and 12D in Australia.
