I think there are limits as to what is "too much" but it all depends, if those things stop you from having a life cause you too busy trying to get ready or shopping then its probly bad, if it doesn't hinder your ability to go out or whatever then I think its fine, I love when a girl takes pride in looking good.
That's her thing. Maybe she is just really into fashion and beauty and likes to look nice. What is wrong with that? Usually girls like that tend to be the most attractive girls so if a guy has a problem with that he's probably a hypocrite because he might be annoyed by the description but guaranteed his head will turn when he sees the finished result.
