Most women don't know how to put makeup on. It looks totally unnatural most of the time. I would rather a girl not wear it, than to wear it wrong. Makeup does advertise that a woman is trying to attract someone, so often a woman wearing makeup will get approached more.
My husband can't tell the difference from my natural face to when I wear my daily makeup. I only put on foundation and powder. However, I used to work at a bar and I started to put on eye make up. He hated it, and I didn't even put on as much as the other girls. I remember going out one night and him begging me not to put on eye makeup during that time.
