Teen starting her first job, who pays for what?

My daughter just graduated HS less then a month ago, she just landed her first job, she will work as much as she is needed during the summer and once college starts, she will only work part time...school will come first . The question is this: Should she be buying for the majority, if not ALL her clothes, entertainment? She is not yet 18, will be in a few months. We argued about this because I have always bought all her clothes, everything she has needed. I will be contributing to her 1st car. I will be giving her apprx 3k towards her car, IF she shows me she can keep this job and save her portion for her car (she needs to save 2-3k) she already has a checking account and is motivated to save. When she starts college in the fall, I will be paying for her classes. Currently she was added to our auto insurance and I told her I would pay for her insurance, however once she buys her own car, she will have to pay for her insurance. She somehow still thinks that I NEED to buy her most of her clothes/makeup,etc.. her words "It's not fair"! I feel since she will be working, she will now be capable of buying most of her own clothing. I do not ask for her to contribute to the household bills whatsoever. I do think she should be respons. for her own clothing and insurance once she buys her car and adds it to my policy. Am I wrong?
