I need a little help here? *please*?

well here's the story, my daughter rose is lacking self esteem. She tells me of these two girls in her grade Kat and Brianna, who are drop dead gorgeous (according to her) She says they are gorgeous and horribly dis-respectful. They both have a myspace with "Provocative like photos" I've noticed from their myspace accounts, that they both have to wear make-up to look the way they do, and they have to do their hair, and wear extra Accessories to look this way...............My daughter doesn't wear make-up, she doesn't do her hair, and she doesn't wear extra Accessories, but she is still beautiful, i tried telling her this, she wouldn't listen, i also told her that looks fade, and one day they'll get old and wrinkly.............still didn't listen............What should i do, she's only 14.5 and has horrible self- esteem?
