I guess the female version would be something regarding hip and bust measurements?
I suppose, as has been said above, there is a range of compromises that you can make. If your face is distorted beyond human recognition, I don't think a massive set of tits or a huge cock is going to change the fact that you aren't attractive.
Christina Hendricks for instance has a godly rack, but her face is a bit off (to me, at least). Given that her face is still, say an 8/10, her 10/10 body puts her around a 9.5 for me. If she had, by contrast, a 4/10 face, it might drag the entire package down to a 7.
Anything below a 7 on either the face or body scale seems to disproportionately pull the total attraction down for me, so I can't answer without something concrete to compare.
