In almost every school in the world the school uniform is compulsory . students have to wear uniforms. The reason must be that the schools administration wants their students to concentrate on their studies instead of their appearance or the they wear, and instead of trying to impress other students by the clothes they wear.
On the one hand, school uniform is important, and it has some advantage: all the students are equal, no body need to be concerned about what he/she wearing, and there is no discrimination. For example without school uniform same students might feel discriminated because they can't buy trademarks and they can't dress like the other students who can. Moreover school uniform economizes time in the morning because it is a waste of time to choose clothes that are good enough and that impress the other students.
On the other hand, clothes reflects what the students think, believe, love, hate, and etc.
To makes all the students wear the same cloths hurts their uniqueness, it means that everyone is he same and no one is special. For example they are some people who love to wear black clothes, big necklaces, and to paint their hair with different colors, compared with people that love to dress with big clothes, big hats and big shoes. With their clothes people express themselves and it is very important.
In my opinion school uniform is very important and crucial because students can concentrate on their studies instead of their appearance, and everybody is equal with no discrimination, and humiliation.
