I think it necessary for student to wear the same school uniforms.
Firstly,wearing the school uniform is able to make students have
a good attitude towards study life.In addition,in order to attract
others' attention,students will spend more money to purcher beautiful
clothes,which will bring parents heavy burtden .What's worse,schools can't form a perfect eniveroment.
As is the saying goes, every coin has two sides.We must recognize the
negative and positive effects of wearing school uniform.
