Beauty is intrinsic to a person, it's got fuck all to do with arbitrary height, weight and measurements. It's the combination of a person's unique physical features that make them attractive, or not.
And anyway this thread asked "Hot body or pretty face?", not whether you'd prefer a "fat" chick or a skinny one. Man some people have scarily superficial/2-dimensional ideas of beauty... Watch less advertisements people. Beauty is about diversity.
Whilst I agree with you to a certain extent - everyone has their beauty, and it shines if they're happy enough even if their body is scarred, overweight or unhealthy in various other ways...
Ideally though, you're not gonna want to pick someone who is overweight, but would do in hope they would pull themselves together, with your loving support, if their personality was amazing.
BUT I seem to remember studies being done over the last few hundred years, surveying and calculating the ideal attractive body measurements. They're nothing like what is advertised now, and therefore I believe them to be as close to instinctive as possible at the moment, with today's current widespread conditioning. For example the "perfect" hip, thigh, bum and breast measurements a man finds the urge to mate with - potential childbearing indicators. There are of course 3-7 sizes of healthy people, the nervous skinny people, up to the heavyset slow people, so there must be various actual measurements, to fit in with proportion.
There must have been studies into what a woman looks for too - male proportions etc.
To be honest, from my knowledge and observations, I would not be surprised at all if "pi" or "phi" came into the perfect proportion calculations. I will share later, I'm not able to multi-tab online right now.
