>>3386033<---this and similar examples.Slim and fit with natural curves.
The curves you can't change though so you can't really count it as something to work towards.
Same deal with the face but weight and makeup can change a face.
Essentials would be.
1. Slim. The girl in the pic is about as low body fat as would look good, lower would be bad. Higher could actually be ok if she had the genes to make it look good, but not too much higher. 2. Fit. There are plenty of 'slim' girls with fat arms and tummies and no muscles, this is a major turnoff. The girl in the pic has visible muscle defenition while not being muscular as such. You only get that by having muscles and having low body fat %. (Someone should dig up that pic of the super hot pole vaulter)
Basically for any body type, size of t&a, race, face etc men prefer the slim and fit examples. I'm emphasizing this because it's something that can be changed whereas the other things can't.
Also men have vastly different preferences in terms of t&a, race and face, but the vast majority prefer slim and fit.
