I'm still wondering why anyone gives a crap what other people wear, particularly if those other people aren't part of your school.
Doesn't everyone have enough on their plate just taking care of themselves that they gotta dictate whether someone they've never met can or can't "wear their kerrotty uniform?" What are we, politicians?
Give it a rest. If women can wear pants-suits, men can wear dresses, old people can wear their pajamas to Wal-Mart, and we can all go pee in whatever bathroom we want, then no one gives a fat fiddler's fart if anyone wears gi pants or full on ninjer cammo, and they certainly don't care whether or not you think they meet your standards of training based on sweatiness.
