Update: It's hard to disagree with this observation:
What these adults didn't factor in, was the students are clever and love the idea of "organized chaos." I PROMISE you, on day one of school, nearly 2/3 of the student body will intentionally arrive out of dress code, forcing the administration to realize they don't have enough jump suits. Those who are "lucky" enough to wear one will think it's cool and it will almost become trendy.
The students may not know anything, but they're not stupid.
