Well my school has uniforms. Grade 7-12 have to wear formal every Monday, guys probably have it worse as they have to wear a tie and have their shirts tucked in to pants with belts. Girls have a button on tie and below-knee skirt. Then we have casual which is a shirt in the school colours and knee length pants though most girls adjust the length (make them shorter). Oh and we have to wear black leather shoes.
On event days such as the sports carnival we are allowed to dress up. But we are suppose to have sleeved shirts and a few other rules I can't remember but teachers normally let it slide (It's just one day after all).
Teachers manly focus on the whole; no jewellery apart from one set of earrings, black leather shoes and no non-school jumpers.
In younger grades they seem to care about nail polish as well and last year there was this huge thing that if your hair touched your collar it had to be tied up.
A few teachers are much harsher than others for example some will simply tell you to not have the jewellery showing (hiding it under your collar) while others will send it up to the office making you collect it later in the day.
I remember when I went to a Private Christian School ;A; I always had to wear a jumper, and the guys always wore these weird suit-like outfits. I eventually switched over to the male uniform xD My 4th grade teacher couldn't care less. I had to transfer out after that xC My parents realized that all the 'Bible Classes' weren't helping me become a better person, and they really didn't want me to sit through the anti-LGBTQA speeches.
