i think it's more of a trail an error when you first start to put on makeup. the best thing is to do a little bit at a time. don't go all out and do your face, eyes, cheeks, lips, etc... unless you make it really natural. if she has never wore makeup before and she is planning on wearing foundation it might look funny to her in the beginning. i rememeber when i was fooling around wtih my sister and i put foundation on her face it looked really weird because i wasn't use to her wearing anything.
