Uniform Is Not Necessary

                                                  UNIFORM IS NOT NECESSARY 

                   I think school uniform is not necessary for students.Firstly, uniform is very expensive.Furhermore, when it's dirty ,you can't wear other clothes.Because it is compulsory. Secondly, school's aim is learning something,the goal is not to wearing uniform.I think all wearing clothes by students ,is a school uniform.To sum up, students don't need uniform.
