What are the advantages of wearing a uniform?

In Taiwan, we have to wear it since elementary school. I think there is truly have some advantages of wearing uniforms.
For example, the parents don’t have to spend the extra money to make their children to meet the latest fashion. They can spend less money on clothes and fashionable apparel. Uniform can also help to eliminate the tense culture and economic difference s among the students. The parents’ income is no longer determined how well their children dress at school. And the there is also a possibility of violence due to the article of clothing. If a student is dressed up similar to a member of a gang, another student who is not in favor of that gang might plan an attack towards that person. Every parent would like their children to be as safe as possible during school, with uniforms their children will be safe and secure at school. The last is that the school uniforms can help to promote discipline inside of the school. This structure creates a strong learning environment and improves the students’ behavior and attitude towards studying. Because of the learning atmosphere created by uniforms, students are more likely to concentrate on their schoolwork.
I think the advantages of uniforms are by-far ahead of the disadvantages of uniforms. Therefore, I believe every school should use uniforms.
