School Uniforms
Most schools accept the students to choose between a couple different options on colors for the polo, pants, and skirts. Along with this students have a series of sweatshirts they can wear and other apparel so with the uniforms the students still have some freedom on what they can wear. At the same time there can not be alot of different options as that makes the uniform system broken.
