Size Chart: Sister Sizes for a 38 Band Size Based On UK Sizing

This is our sister size chart for a 38 band size. Find your current bra size in the first column, then find out what sister sizes we’d recommend for sizing upwards or downwards.

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.
