How to measure

Under-bust or band size

  • Wrap tape measure just under the breasts, around the rib cage. This is your underbust measurement. Round up to the nearest even number to get your band size. Then subtract your underbust measurement from your bust measurement .
  • The result is your cup size according to the following:
    • AA = 1/2"
    • A = 1"
    • B = 2"
    • C = 3"
    • D = 4"
    • E/DD (US) or DD (UK) = 5"
    • F/DDD (US) or E (UK) = 6"
    • G (US) or F (UK) = 7"
    • H (US) or FF (UK) = 8"
    • I (US) or G (UK) = 9"
    • J (US) or GG (UK) = 1
