Fitting Guide

1. Measure directly under your bust with your bra on. Take it to the nearest 5cm. This is measurement A.

  • 70 cm = Bra size 10
  • 75 cm = Bra size 12
  • 80 cm = Bra size 14
  • 85 cm = Bra size 16
  • 90 cm = Bra size 18
  • 95 cm = Bra size 10
  • 100cm = Bra size 22
  • 105cm = Bra size 24

2. Measure from the sternum to the spine across the fullest part of your breast and multiply by two. Take it to the nearest 5 cm. This is measurement B.

3. Now take measurement A from measurement B to obtain the cup size.

  • A difference of 13 cm needs an A cup
  • A difference of 15 cm needs an B cup
  • A difference of 17 cm needs an C cup
  • A difference of 19 cm needs an D cup
  • A difference of 21 cm needs an DD cup
  • A difference of 23 cm needs an E cup
  • A difference of 25 cm needs an F cup
  • A difference of 27 cm needs an G cup

e.g. If your under bust measurement was 85cm (measurement A) you would be bra size 16. If your over the bust measurement (measurement B) was 100 cm, you would take 85cm away from 100 cm (measurement B – measurement A) to get 15cm. This means B cup. So your bra size would be 16B.
