How to Calculate your Cup Size

  1. Use a dressmaker’s measuring tape to measure the circumference of your rib cage, just under the bust.
  2. Take the measurement of the bust at nipple level.
  3. The difference between these measurements determines the cup size:

12-14cm = A cup

14-16cm = B cup

16-18cm = C cup

18-20cm = D cup

20-22cm = DD cup
