Leaflets which explain how to measure yourself are also available. Remember though that measurements are only a guide - you should always try a bra on to be sure it fits well. When you're trying on a bra practice some normal movements, like bending and stretching, to make sure it doesn't ride up or become uncomfortable. If you have a well fitting bra, it will prevent common problems like strap marks on your shoulders. You may not always take the same bra size - styles and makes vary.
Some specialists make bras up to a GG fitting.
Most women have one breast larger than the other. Always fit the larger breast when choosing a bra. Hide any differences by adding light padding or taking in the bra on the smaller side. If your breasts are a different size or enlarge just before your period, stretch bras may be more comfortable. Underwire bras Be particularly careful to choose an underwire bra which fits correctly.
