@ScOtTsKaTz - Well because band size is just measuring under and that's it! (Some sites say to add 4in which makes NO sense to me because if I have the measuring tape wrapped around me I can SEE 4 more inches would make the bra drop to my stomach. WHY ON EARTH ADD!?) But for the bust you have to figure out the size from the difference in inches and I just can't believe the charts when they say 5in=DD. I mean, isn't DD getting into the jumbo sizes!? I don't have jumbo boobs, look at me!! I realize I've been wearing B incorrectly for God-knows how long, so I'm either a C or a D (and I'm thinking the D as a "maaaaaaaybe") but DD!? That can't be right, but I don't get how I'm screwing up the measurement. (And it's not because I'm refusing to "add 4in" [which only a couple sites say to do] to my band because then the difference would be 1in and there is no way in HELL I'm an A cup. xP)
