How to measure your bra size and cup
Step 1: Measure around rib cage, just under the breast. This is the band size.
Step 2: Measure around the bust at fullest part of the breast.
To find the CUP size, determine the difference between the 2 measurements:
– If the difference is less than 15 cm, your CUP is B-C
– If the difference is between 15 – 20 cm, your CUP is C-D
