Is 38D bra size big?
Your cup size is the difference between your chest size and your bust line measurement. For example: Your bust line measurement at the fullest part of your bust is 34″ and your chest size is 32″. 34″ – 32″ = 2″. The difference is 2″, which means your cup size is a B cup.
Clothing and Bra Size Information
In 2006, the largest cup size Berlei made for Australian women was a G. In 2019, the largest cup size is now a H, and if need be you can purchase bra that is size 26E. Last year, Bras N Things senior buyer, Jessica Lauppe-Guy, said that the company’s most popular bra size was a 12-DD.
A 38D would be a chest measurement of 38 inches and a breast measurement of 42 inches. A breast measurement 5 inches larger than the band size is a DD and a breast measurement 6 inches larger than the band size is a DDD. Some European brands do have E and F cups. And there is some variance in sizing among the brands.
MM is a large cup bra and a band close to 50 is large, no matter what the cup size…but a 38D is probably closer to “average” than most self conscious teenagers would ever think. I’ve never seen an MM cup size but I have seen several women with a G or H.
