Sister sizing is a clever tool to use when a bra is unavailable in your size, or you prefer a slightly looser or tighter fit in the band of your bra. 

For example, if you usually wear a 14C you could also try the 12D, which has the same cup volume but a smaller band size. Use the following table to find your sister size:

32B
32C	34B
32D	34C	36B
32DD	34D	36C	38B
32E	34DD	36D	38C

Note: while sister sizing is a clever trick that we wish we had learnt earlier in life, it's not a perfect solution, and we recommend trying different sizes to find the most comfortable and supportive fit.
