I think it'll probably still leave room for the schools to keep kids from going to school in anything that would violate present dress codes. Judges have also said in the past that if a child's "First Amendment" causes a disruption of schooling, it is not permitted. Given that tuxes are formal wear and far from anything too outlandish or risque (is that how that's spelled?), I think that schools will still be able to keep kids from coming to school with, I don't know, peacock feathers sticking out of their heads and a sequin bikini. This wasn't "daisy dukes vs. capri-pants". This was pants vs. dress.

Really, the only result of this I think we'll see is that we'll start seeing more girls at proms in pantsuits and tuxes, and maybe the rare guy here or there showing up in a dress.
