Measuring Bra Size & Size Conversion Table

It is important for reasons of health, comfort and appearance to wear a bra that is the correct size for you. There are certain basic measuring guidelines, but these are only ever a guide as we all differ a little in bone structure. When fitting a new bra is not an option before you decide to purchase, you may always call our help line on 01760 447463 or send an email to: customerservices@nicesurprises.co.uk


Return of your bra is always an option if it is not the right fit, although we would ask you to pay the return postage costs. * Please see customer services section on returns.

Measure the chest immediately underneath the bust, keeping the tape as tight as possible. This is the Underbust measurement, which gives you the correct back size.

Next, measure over the fullest part of the bust (not so tightly this time), which will give you chest+breast measurement resulting in the overbust measurement, this gives you your cup size.

Bra Measuring in cm helps to give an accurate size
