School uniform

In our school, there wasn't restriction about school uniform.
we have seen seniors are wearing clothes which they want to wear freely.
But now we can't get right like seniors. I disagree about opinion of school.
first of all, our school uniform makes our feel an inconvenience.
we live all days in school. so, we need more concern for good school life.
I think this is a duty of school.
second, school uniform obstruct our have right individuality.
now, people think individuality for the best important thing. we can't neglect.
third, we can think a hygiene of uniform.
we have to wear a uniform day to day. we can't frequently do wash a uniform.
It makes troubles like a bad smell.
From these reasons above, I disagree on wearing school uniform.
