Wow, that last link is very informative. I could have about sixteen different cup sizes depending on the manufacturer's whim. :)

Sadly, Road Runner bottoms out at a 32" ribcage and Bare Necessities stops at 30. I'm solidly 28. My mother, on the other hand, might be able to do well with some of these links. We're opposites. She got all the ribs and I got all the boobage! :)
