Apart from all the other points made here, I always wonder why uniforms have to look like there has been no development in clothing/fashion for the last 100+ years? Why do they have to look like they are extras on a Harry Potter filmset?
Some schools have uniforms that are just khakis and a polo, but yeah I dunno why a lot of places think blazers and ties are a good idea. I had to wear those in HS and never got used to it-- still hate ties to this day
