How do I get my parents to let me wear make up?

I am 15 and my parents won't let me wear make up. I mean I don't want to put globs of it on, just a little. When I do put make up on they tell me to take it off. It just bothers me when I see a bunch of people wearing it and I can't because of my parents. Also, all of my friends wear it too. And when we go shopping and things like that, all they ever want to buy ahhh what should I do?
