The pro of wearing school uniforms is to help children know about team spirit and sense of unity. For example, team players will wear team clothes in a football or basketball match. The purpose is not only to help them recognise who their teammates are, but also to help them to build and develop team spirit and a sense of unity. People normally do not wear the same clothes without a purpose. Therefore, the wearing of school uniforms is a good way to help students learn about the meaning of wearing the same clothes.
The con of a school uniform is that it wastes money. Children will not wear their school uniform during their holidays. Parents still need to buy casual clothes for their children. It adds an extra financial burden for parents.
In conclusion, wearing a school uniform has pros and cons. However, wearing a school uniform has become a tradition. Therefore, many children still wear a school uniform as usual.
