What is the bra size 40B? Some may wonder if there really is a 40B bra size. The answer is absolutely yes!Read more...
The "40" refers to the band size and the "B" refers to the cup size. So, what are the sister sizes to a 40B 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 40B. For example, a 40B bra size has sister sizes of 38C and 42A. These bra sizes – 38C, 40B and 42A – 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 38C has a smaller band than a 40B, and a 42A has a larger band than a 40B. If a 40B bra size fits you, this generally means your under bust measurement is 35 to 37 inches and your over bust measurement at its fullest point is around 42 inches.
Bra size 40B is 90B in Europe and Japan, 105B in France, and 18B in Australia.
