Sister sizing allows you to find your perfect fit. Sometimes after measuring yourself it is possible that your size may still need to be adjusted.
The following chart shows sister sizing for each bra size. All of the sister cups in the same row are the same size.
Sister sizing is like a seesaw. If you move up in the band, move down in the cup and vice versa. For example if you find that a size 34E fits well in the cup, but is too big around the band, go down to the next sister size in the row and try a 32F.
HM Collectives Fitting Quiz will help you find the right size. Our fitting Video is another great way to make sure you have the correct fit. Still unsure?
