I'm a 20 year old female... I have black hair, ivory skin, brown eyes and am flat-chested. I am thin also. I don't think I'm an ugly girl but have got to thinking. I haven't been asked out or even approached. I hear of girls being approached 5 times daily. I went to the mall recently with my little sister and there were tons of guys my age there and they looked at me and would walk on by. I felt invisible and ugly. I need input.
