Beauty is in the eye of the beholder? I am sorry to break it up to you, but that is not true at all. There is such a thing as universal beauty and it has scientific prove as well.
Basically somebody who is ugly of she is a girl: Is if her body to hip ratio is closer to 1, that is the closer hips to waist ratio are to 0 the more attractive she will be (no there isn't a person in the world with a rating of 0), because she will have a small waist compared to her HIPS which means she is more attractive.
Small eyes or frog eyes for that matter, big nose, pointy nose, small lips, really bushy eye brows, or reall thing eye brows, too long of a face, her mouth is too big, big ears, big molds, fat, too tall or too short and an uncemetrical face over all.
