Step 1: Measure your Underbust

The part underneath your bust line.

E.g. if your underbust measurement is 71cm, your Band Size will be 70 (refer to our table below)

Step 2: Measure your Top Bust

The fullest part of your bust

Step 3: Top Bust – Band Size = Cup Size

Find your cup size using the table below.

E.g. If your top bust is 85 and underbust is 70, the difference will be (85cm – 70cm) = 15cm. Your cup size will be B and bra size will be 70B.
