What Are Sister Bra Sizes?
If you are finding that your usual bra size isn't fitting then this may be down to a different manufacturer, different brand, or even different style of bra which may mean you have to look for a different size for this bra.
Sister bra sizes are the sizes that surround your bra size. With the size of bras sometimes differing because of the manufacturer, brand, style and even country, it is good to know about sister bra sizes so you can try other bra sizes if the one you have doesn't match your usual 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.
If you are not sure which sizes to try then please give our team of friendly and experienced bra specialists a call on 01439 798388 as they will be happy to help.
