Maybe she will go for the Goth Look, heavy white makeup, red lips and all cloths in black black black.

I do understand however, my daughter is 21 now and 15-20 something is SUCH a difficult time for mom's and daughters. It does get better however. Until then I agree with the other posters, choose your battles wisely. If she isn't smoking, drinking, doing drugs and having sex count yourself luckly, most 15 year olds are doing at least one and hiding it from their parents. Good luck. Reading some Erma Bombeck might put a smile on your face.
