Women's Bra Fit Guide

Wrap a soft tape measure firmly around your rib cage, just under your bust. Keep it snug but not tight. Note the number in centimetres and round down to the nearest whole centimetre. 

 Step 2: Measure your bust 

Wrap the tape measure around the fullest part of your bust. Keep it comfortably loose. It’s best to wear a soft, non-padded bra for this step. Round up to the nearest whole centimetre. 

 Step 3: Use our bra size chart to find your size 

Use your underbust and bust measurements to find your Australian bra size on our bra size chart below.

Use your underbust measurement to find your body size in the first column. For example, if your underbust measures between 73-77 cm, your body size is 12. 

Next, find the number that matches your bust measurement along the same row. The column your bust measurement falls under shows your cup size. For example, if your body size is 12 and your bust measures 90 cm, your cup size is B. So, your bra size is 12B.
