Measurement 1:
Measure around your body directly underneath your bust. The tape should be held firmly to obtain an accurate measurement
Measurement 2:
Measure around the fullest part of your bust.
To determine you bra size, take measurement 1 and add 5 inches, so if you measure 31 in this suggests that you should wear a 36 inch bra.
If your mesurement is in between go up or down to the nearest even number; if the final number is exactly an odd number always round up.
To determine your cup size please use measurement 2 and the following table.
If the measurement is the same as the Bra size you should be Cup Size A
If the measurement is 1 inch more than the Bra size you should be Cup Size B
If the measurement is 2 inches more than the Bra size you should be Cup Size C
If the measurement is 3 inches more than the Bra size you should be Cup Size D
If the measurement is 4 inches more than the Bra size you should be Cup Size DD
If the measurement is 5 inches more than the Bra size you should be Cup Size E
If the measurement is 6 inches more than the Bra size you should be Cup Size F
If the measurement is 7 inches more than the Bra size you should be Cup Size FF
If the measurement is 8 inches more than the Bra size you should be Cup Size G
If the measurement is 9 inches more than the Bra size you should be Cup Size GG
