I have had to wear uniform in every school I've been to. In primary school (UK) it was a black jumper with school/town insignia, black trousers and an awful bright yellow polo shirt. In high school its the same but a white polo shirt instead. It's also far more relaxed, I see people wearing all sorts of t-shirts under school shirts. The teachers don't seem to mind unless you turn up in jeans. I have no problem with school uniform as it takes pressure off you of what to wear. I don't mean trends because I rarely bother keeping up with them. We do have one day a year when you don't wear uniform but you give a pound (£)to charity to do so and then EVERYBODY wears jeans
