Should students be required to wear uniforms to school?

I strongly agree with the point that students should wear school uniforms. Wearing school uniforms give less financial burden to both students and their parents, since they only have to buy the uniform for just one time for wearing more than 3 years. On the other hand, just wearing normal clothes will give stress to students because they think they should wear lots of various clotes everyday. It'll cost a lot, which might be a tremendous financial burden to them.
