What Are Sister Bra Sizes?

Sister bra sizes are the sizes that surround your bra size.

How to Find Your Sister Bra Size
When you’ve located your current bra size on the chart, you’ll be able to read across and discover your sister sizes. There is an option to size up, if the bra you’re trying on feels too small, and an option to size down, if the bra you’re trying on feels too big.
If you go up in band size, you may need to go down in cup size. If you go down in band size, you may need to choose a higher cup size. This is just a guide - please note that sister sizing can be quite complicated as you may need to adjust both the cup size and the band size to get the best fit.
Sister sizes can be other sizes that surround the initial size. Take a look at our example chart based on UK sizing.
