For as long as the school system has existed, so has the rule of all attending students having to wear a standardised uniform. This is a common sight across the world from the ages of five to late teens, and though it is certainly a school tradition that seems to have largely stood the test of time, there has always been different varieties of opposition to the rule, primarily from students.
Teachers should definitely wear school uniform. I am one of the many people that think teachers should wear uniform. Honestly I don't get why students wouldn't want teachers to wear it in the first place like seriously they brag us student all day to wear proper school uniform and shoes and everything but they don't look at them self first.
