Please correct my paragraph about school uniforms. Thank you

Should all high school students have to wear school uniforms?

Many people think that wearing school uniforms is compulsory for high school students. In my opinion, I totally agree with this for three reasons. First, school uniforms make students feel equal to others. They don’t distinguish between poor and rich ones. For example, students wearing old-fashioned clothes will not be discriminated by other students. Second, school uniforms help students not lose too much time to decide what they should wear to go school. They don’t need to think which shirt matches with their trousers, so it will save a lot of time to prepare before going to school. Finally, uniforms make the uniqueness which makes students proud of their school. It can motivate students to study harder and reach more achievements in their school performances. In conclusion, I personally feel that wearing school uniforms is very necessary for high students.
