I agree with wearing school uniform in school ( not university )
There are three reasons.
One reason is that if we wearing school uniforms we can reduce the costs of buying many clothes.
for example, it can be helpful to students who can't afford to buying clothes often.
Another reason is that we feel intimacy to people who is dressed same with me and
it makes students feel more sense of belonging to school.
A third reason is that wearing any clothes makes confusion to students.
for instance, other students can make trouble in our school, feel the gap between the haves and the have-nots in students, etc...
So i am for wearing school uniform.
what do you think about my opinion?
