Maybe I'm opening a can of worms, but I'm sure everyone's heard this one: "what would Barbie's bust size be if she were an adult female?" It's interesting that no one can come up with a definite irrefutable figures. I've seen everything from 35-23-32 (5'9") to 42-18-33 inch (5'6"). I know Barbie figure has changed over the years, and varies even by region (the Asian model is less curvy). I'm not siding on any side of the issue. Just pointing out how math is not always as empirical as it should be.
