When I went to high school dress code was strictly enforced. Not uniforms or authoritarian bullshit, but no sagging pants, girls must abide by shorts and skirts longer than their fingertips (leggings let you bypass this), and a few other things.
Of course, things have changed since 2010 and the school has deteriorated, including letting a rodent infestation get out of control, and my cousin's kid does talk about furries wearing tails, and apparently, this is tolerated now. Culture wars got to it, I know the Gay-Straight Alliance also got larger and more prominent (it used to be a few tiny signs, by 2016 they had their own t-shirts, given what I saw someone wearing to a store once).
