My daughter dresses in themes, too ( but she's only in K). She'll be a kind of plant with the right colors, etc, or she'll make up some character, or be one of her heroes like Elphaba or someone, but mixed with a different situation for the character.

I appreciate how uniforms simplify things, but I'm mostly fine with a well-enforced dress code (for things like beer tees and vulgar print, which yes I've had to have kids turn inside out) but mostly I think hair and stuff should be free from rules. The idea of forbidding color (like in news stories) is just kind of wacky to me. But then again I'm in California.
