Sister Sizing is slightly confusing lingerie jargon. But we’re here to give you the simple run down!
Sister Sizes are similar sizes that fit your measurements. The idea is if you go down a back size (underband) and go up a cup, you should have a fairly similar fit. And the same if you were to go up a back size and down a cup size.

In the chart, find your size, then look at the sizes directly to the left and right of your size to find your sister sizes.
