Girls can just as many doubts about their looks as guys do. In fact I don't you will find any model who is 100% satisfied by their looks. Many wear makeup to hide acne scars or to feel better about their self while improving their looks. But would a guy even look at a girl unless she was all dolled up, or because she looks bloated or dressed in grungy clothes that make her look less than attractive?
Would you give any of these women more than a cursory look?
Can you identify any of the women in the photos? They are all celebrities sans make up.
