Bra Size Charts and Fitting Guide

How to order the right bra size from Lux and other UK brands:

First you need the band size.

Measure around your rib cage, the tape measure should be horizontal around your body. This is your underbust measurement THIS IS NOT YOUR FINAL BAND MEASUREMENT FOR UK BRAS.

 

Add four inches onto your underbust measurement to get the band measurement. So if your underbust measurement is around 28” you’ll be needing a UK size 32 bra, 30” – size 34 band, 32” – size 36 band and on in 2" increments

CUP SIZE

Cup sizes are named alphabetically e.g. A, B, C… and relate to the volume of the cup in relation to the band size of the bra. The theory is that if your bust measures 1" larger than your underbust then you are an A cup, but the whole system is imprecise and confusing.  In practice most women have an idea of their cup size and we can use the bras they already have that fit to come up with a very good estimation.

To add to the confusion different countries have different names for the same volume
