Ill-fitting undergarments and clothing can leave you looking lumpy and bumpy as well as being uncomfortable throughout your day. Learn to take proper bust measurements so that you can find a properly-fitting bra, as well as tailored dresses and tops that make you look your best. You will feel more confident and look more professional in properly-fitting clothing.

Put on the best fitting bra you own that isn't padded. Adjust the shoulder straps if necessary. The straps shouldn't dig into your shoulders. Lean forward and use the cups of the bra to scoop your breasts into the cups to make sure you are completely in the bra.

Wrap the tape measure around the fullest part of your breast, level with your nipples. Keep the tape measure parallel to the ground as you do this. Round an fraction of an inch up to the next whole inch. This is your bust measurement.

Measure around your chest, at the bottom of your bra, just below your breasts. Keep the tape measure parallel to the ground as you do. Round any fraction of an inch up to the next whole inch. Add four to the number if it is even and five if it is odd. This is your band measurement.

Subtract your band measurement from your bust measurement. The difference between these two measurements gives you your cup measurement. No different between the two measurements means you are a cup size AA. A difference of 1 inch is an A cup. A 2-inch different is a B cup and so on.
