If it looks natural and doesn't look like you've over done it then yes I think it's attractive.
I'm not into girls who plaster make up on, to me girls look most attractive when they have a more natural look. there's nothing wrong with wearing make up and if it makes you feel better then you should wear it :)
I don't notice that much unless it is a girl with whom I am quite friendly or If I am interested in her. But Right make-up matching your personality, dress and the occasion is very attractive.
But , when we see a girl, who looks quite attractive in simple or in light make up. And she does something very dark, and that does not match her look. then I sometimes think , It is weird. But Its her choice. If she feels comfortable that way, let her be happy.
depends on the guy,some guys like wearing makeup themselves,some like the whole ''fully made up'' look,some like natural makeup,some hate makeup in general. the safest way to go is natural makeup-you still look good,but you don't look fake.
