To ensure your bra is the correct size and fit follow the following steps:

Measuring for your bra size

1. Measure the chest directly under the breast, keep the tape measure tight. This is the underbust measurement.

2. Whilst wearing your best fitting bra, measure gently over the cups at the fullest part of your breast. This is the overbust measurement.

The difference between the underbust and overbust measurements determines cup size.

Now refer to the chart below. This will provide you with the correct English bra size that is standard throughout our site.

3. E.g. Underbust measurement of 80 cms and overbust measurement of 97 cms is a 36C English Bra size.
