So What is a Bra Size?
Our society is focused on bra size. It’s in the magazines, television ads, and movies. This has a not insignificant impact on women and their overall sense of femininity. But how many people really know where the measurements come from and what makes the difference between one size and another?
Let’s start off with a break down of the bra size. I’ll use 34B as an example. The number is the band size and the letter is the cup size. The measurement of the band size is performed by placing a measuring tape around the ribcage just under the breasts. This measurement is rounded up to the nearest even number. The breast or bust size is then measured by placing the tape around the fullest part of the breasts. The cup size is then determined by the difference between the band size and the breast size in inches. A one inch difference is an A cup, a two inch difference is a B cup, a three inch difference a C cup, a four inch difference a D cup, a five inch difference a DD cup, etc. And although there are variations and estimations, this is a good rough guide to figuring out one’s bra size.
