About the bra cup sizes, they relate to the difference in size between how many inches your chest is around just under your boobs, and how many inches around you are when you measure around your back and over the fullest point of your boobs. Ok, I used to measure women for part of my old job selling bras and stuff, so here is how you do it:
**Bra Sizing Class!**
Take a measuring tape(you know, the flexible kind which is measured by inches) and wrap it around your body just under your boobs. Where the loose end of the tape(near the 1 inch mark)overlaps the rest of the tape, that is your chest measurement. When pulled snugly, average measurements are between 29-40 inches. Now, take the tape again and measure around your chest just like you did the first time, but this time have it up higher so that you measure around the fullest point of your boob. The tape should not be either tight or loose this time. This is your second measurement, your cup size. Now, compare the two numbers you got. If the cup size measurement is:
* 0-1 inches larger than your chest measurement, you are an AA or an A cup
*around 2-3 inches larger you are a B, or small C cup
*around 3-4 inches larger, you are a C cup
*around 4 inches makes you about a D cup
*5+ inches makes you a full D or possibly DD
the larger your breast measurement is, the larger the cup size you are. This is all approximate, so it's always best to try on 2 different sizes of bras when you go cup bra shopping.
h34r: It's not like we're saying "Hi my name is ___ and my last name is ___ I live in ___ come make fun of me!" Personally, I'd be more comfy talking to some other girls online that live somewhere else than talk to my friend that lives in the same town that will probably blab to someone. But, of course, thats just me.
