Some schools have uniforms so rich kids can’t take the ‘poorer’ kids down because of what they wear. I went to a school where a uniform was a… Polo shirt (IT WAS THE WORST THING I EVER WORE AAAH) and the printed on badge came off when my mom ironed it 
I think that the school uniforms are very unpractical and take away our choice to express ourselfs through our clothes
