I was just wondering this yesterday, I would love to subtract the weight of my breasts from my overall weight -- I'm a 32DDD. (Double D if I don't mind tucking my boobs back in all day.)
I would love to be able to buy bras at Victoria Secret, but alas, nothing ever fits. I'm stuck to ordering bras online from Frederick's of Hollywood. (The boyfriend is more excited than I am when the catalogs arrive than I am, he flips through them first!)
Would love to be a manageable C/D cup and have a little more in the back! I have no butt.
I don't mind being busty, except that running presents a problem, I've yet to find a regular sports bra that works. I usually have to wear a really tight regular bra with a super tight XS sports bra over it and hope for the best.
