Find your best fitting bra

1) Wrap a tape measure snugly around your body and below your bust. After breathing out, take your measurement. If it's an even number that is your band size, but if it's an odd number, round up to the closest even number.

2) Wrap the tape measure around your chest at the fullest part of your breast. Subtract your band measurement from this number. If the difference is 1 inch, then you are an A cup; 2 inch, then you are a B cup; and so on, through DDD.
