Why schoolchildren should wear uniforms to school?

a school uniform was very important

Explanation:

A school uniform teaches students to dress smartly and take pride in their appearance ... Perhaps most importantly, a uniform means students don't have to worry about peer pressure when it comes to their clothes. When everyone is dressed the same, worrying about what you look like isn't so important

A school uniform teaches students how to dress smartly most importantly, because there gangs and violence now about color blue and red so it's better for students to wear uniforms in my opinion just to save life's.
