Find alternative bra sizes with the same cup volume but different band sizes
Your current bra size is 34C. Sister sizes have the same cup volume but different band sizes.
Sister sizes are bra sizes with the same cup volume but different band sizes. When you change the band size, you need to adjust the cup size to maintain the same volume:
- •Go down a band size, go up a cup size
- •Go up a band size, go down a cup size
For example, if you wear a 34C, your sister sizes would be 32D (smaller band, larger cup) and 36B (larger band, smaller cup).
