> I think you overestimate how many women care about the letter associated with their cup size.
I would have thought women cared at least as much about the circumference number. That's what they worry about in every other item of clothing; that's why the same clothes are a smaller size at high-priced stores than they are at low-priced stores. The letter is a measurement of whether you have a flat chest, but the number is a measurement of whether you're fat!
