To establish your band measurement, measure directly under your bust. Place the tape measure around your torso, just under your bust. Check in a mirror side-on that the tape is level and straight around your body. Take a firm measurement.
To establish your cup, measure around the fullest part of your bust. Check in a mirror side-on that the tape is level
and straight around your body. Take a loose measurement, rounding up not down.
For example if you measure 32 inches around the rib and 39 inches around the chest your bra size will be 36D.
