The Art of Fitting
Every bra size has a sister size. It is the bra size on either side of your “true” size. This will have the same volume but in a different band size.
To find your smaller sister size, choose the next band one size down and increase the cup letter by one. Please see the example below:
If you are a 34G your sister down would be a 32H. This bra will have the same cup volume but a smaller band.
Sounds Like Too Much Trouble to Calculate?
We wholeheartedly agree!
In the Elizabeth Valentine shop or in the My Fit form, you simply enter your largest overbreast measure and your band size separately. You don’t have to worry about calculating a sister size, or a bra size at all, for that matter! We do that work for you.
How do I find my sister size in your charts?
Because we have such an array of sizes and show international conversions for each band size, we cannot put them all into one chart.
Once you know your overbreast measure you can select a different underbust tab on the left and follow along the row for your volume (OB). That will be your sister size for that band.
