Dora Larsen Size Guide

Sister sizes are bra sizes that have the same cup volume as your current bra size and can be a good way to find an alternate size if you need one. To calculate your sister size, you go up a cup size and down a band size or go down a cup size and up a band size. E.g if you are a 34C, you can try a 32D or a 36B.

Find your usual size on the chart below and move across right or left to see your sister sizes.
