Some people think that students should wear school uniforms, because it can not only save students' money but also improve studies. Besides, students don't have to waste time think what they should wear every day except on weekends.And most important thing is that people can see the unity of a school.
However,some people don't think so, because they think the school uniform is ugly and can not express students' characters.
Nowadays, a student can have several suits of school uniforms. Students can wear different school uniforms in different seasons. And school uniforms have more beautiful styles in order to make them in fashion.
In my opinion, different uniforms show different jobs. So it is necessary students to wear school uniforms on weekdays.
