Bit fitting
Measure around the body directly under the bust while wearing a bra. If the measurement is an odd number add 5", if an even number add 4"... e.g. 35" + 5" = 40", 36" + 4" = 40". This is now your bra size. For the cup size, measure the fullest part of the bust, subtract your bra size from your cup measurement. If there is no difference you require an A cup. Consult the cup size chart below.
