I am sooooo disappointed in this child's parents.
Life is definitely about picking your battles, and this is the wrong one to pick. Regardless of the school's reasoning for creating the rule, they are 100% in the right to create and enforce it. Anyway that she shakes it, she's going to lose. The rule is not outstide of the boundaries of normal dress codes, most people are not going to be sympathetic to her preference, and she voluntarily chooses to attend this school that happens to have a dress code. I can't see where anyone will support her enough to help her win. I'm sad that her parents would let her walk into such a losing battle. I have to agree w/AlphaFrog that my parents would have definitely nipped that in the bud. While I think that I feared my parents far too much for them to need to do anything more than TELL me to go change my hair color, they certainly would have enjoyed making my life hell if I had pressed the issue.
