Expressin an Opinion-2-revised

I support that students wear uniform for school.  First of all, I think it is not troublesome since students don't have to worry about what to wear.  Some students may spend too much time thinking about their dressing, so if everyone wears uniform, they don't have to waste time worrying about it.  Moreover, teachers and school guards can identify the students easily.  If students wear their own clothes, it may be difficult to tell them from strangers and the security in the school may be threatened.  Last, wearing uniform can boost a sense of belonging to the school.  Students may feel closer to one another when they wear the same uniform.  According to the statement above, I think it's good for students to wear uniform.
