Many retail stores do not carry this size, but fortunately HerRoom has a great selection of bras and swimwear in this size. The "30" refers to the band size and the "C" refers to the cup size. What are the sister sizes to a 30C bra size? There are several. A sister bra size is a bra size where either the band, cup or both are just one size up or down from 30C. For example, a 30C bra size has sister sizes of 28D and 32B. These three bra sizes – 28D ,30C and 32B – all represent bra sizes 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 28D has a smaller band than a 30C, and a 32B has a larger band than a 30C. If a 30C bra size fits you, this generally means your under bust measurement is 25 to 26 inches and your over bust measurement at its fullest point is around 33 inches.
Bra size 30C is a 65C in Europe and Japan, 80C in France, and 8C in Australia.
