Yes, with a qualification:
The uniforms have to be comfortable, and to reasonable degrees of strictness. Here's what I mean:
I went to two schools for secondary, both of which shall remain unnamed.
The first one (I was only there for a year) had strict guidelines requiring suits, ties, regardless of what time of year. We had to wear their socks (I wish I was fucking kidding) and wear their bags, neither of which were particularly good. They also had strict guidelines about facial hair (Specifically you cannot have any ************) and hair. We also had to change into an entirely different PE outfit that wasn't assisting in the matter of how much crap we have to carry around, and because of that we had to spend the entirety of our recess and lunch breaks changing. We couldn't even change out on our way home, and sometimes the principal would wait at the train station to make sure we adhered to those petty rules. And to top it off, the uniforms were fucking expensive.
The second one was by comparison far more laid back. They didn't care about what bags, socks, or shoes we wore. They didn't care how we did our hair, be it facial or on your cranium. We had two choices of everyday uniform: Cargo Pants/shorts/skirt (they were fine with men wearing them I should point out) and a light polo shirt, or a suit which only a few mad bastards would pick. For winter we could wear coats, hoodies, parachute jackets, jumpers, or just go without if you're part Nord. For PE, all we really had to change was our shirt, and it was all pretty inexpensive.
The latter was a good example of uniform done correctly. It made it clear who we were on campus, but it didn't dig too deep into our parents pockets, it was practical, reasonable about it's guidelines, and comfortable.
