This is just based on looks:
10: Not the perfect girl for everybody, but your perfect girl, meaning the girl you've always dreamt of. She's not perfect, but she's your ideal girl.
9: Perfect looks, but she misses that "I don't know what" that would make her a 10.
8: Really beautiful girl, with maybe a couple of minor unnoticeable aesthetical flaws.
7: The pretty girl next door.
6: She's not beautiful, but not ugly either. She's a hair better than average.
5: You wouldn't notice her in the streets, because she's a really normal girl.
4: Unattractive (too much make-up, ugly face and average body, etc...).
3: Ugly, could be because of her face or a really fat body.
2: Either fat AND really ugly.
1: The opposite of the 10.
