What are bra sister sizes?
Every bra size is surrounded by a set of bra sister sizes. These sister sizes have a different band size and a different cup size.
However, the cup volume of these sister sizes is the same.
In this chart, you’ll see the sister sizes of 36C are 34D and 38B.
I myself have 3 different bra sizes that fit me just fine.
I have one bra size I wear the most. Sometimes I go for a band size 36 instead of the 34 I usually wear. In this case, I go down a cup size to keep the same cup volume.
The cups in a 36 are also a bit wider set and I find this sometimes better for me.
Also depending on the brand and bra style, I try different sizes and actually own different sizes.

- Knowing about bra sister sizes will make shopping for bras more fun. You know what sizes to look for. And depending on the brand and bra style you may wanna choose a different bra size than you usually wear.
