## Find the right Band Size

To find your band size, put on a non-padded bra that fits you well. Find a measuring tape, and stand in front of a mirror. Wrap the tape around your body just underneath your bust. The measuring tape should be horizontal to the floor, and quite snug.
The measurement in inches is your band size. If it’s an odd number, round down to the nearest even number. Check the below US Bra Size conversion tables including the band size chart in US size, inches and centimeters.

## Find the right Bust Size

To find your bust size, measure around the fullest part of your breasts.

## Find the right Cup Size

Take the values of your Bust size (breast size) and subtract the band measurement, e.g. if you measure 31 underneath your breasts, and 34 around, the result is 34-31 = 3. Use the result to find your cup size in the US bra size charts below.
