I went to buy a strapless bra for my upcomming cruise...and guess what I went from a C to a B. BOOOOOO(BIES) On a lighter note I had to take my size 5 shorts back because they were so big!
To all less-endowed gals I'd advise: It's no use to obsess about size. Yes, your A-cups can please. You don't need double-Ds! Lord above, you're as bad as us guys!
If it feels good, do it! And if it smells good, eat it!
