Getting A Great Fitting Bra.

Have a friend help you with the measuring, you will want your measurements to be accurate.

How to measure for the band.

Keeping the measuring tape parallel with the ground, measure around your bra directly under your bust after expelling all air from your lungs - you want this measurement to be as small as possible. Round all fractional measurements to the nearest whole number.

If the measurement is even, add 3".
if the measurement is odd, add 4".

How to measure for the cup size.

Standing straight, with your arms at your side, measure at the fullest part of your bust (while wearing a non-padded bra) making sure the measuring tape is parallel with the ground and not binding.

Round all fractional measurements to the nearest whole number.

Calculate your cup size.

Subtract your band measurement (step 1) from your cup measurement (step 2). Generally, for each inch in difference, the cup goes up by one size.
