Bra sizing simplified
Bra sizing is based on two measurements: the band size and the cup size.
To determine your band size, measure around your rib cage, directly under your bust. Round your measurement to the nearest whole number.
To determine your cup size, measure around the fullest part of your bust. Subtract your band size from this number, and use the difference to find your cup size on the chart below.
