I think it is necessary for secondary school students to wear uniforms when they are at school.
Firstly, wearing uniforms encourages students to be proud of being students of their school because they are wearing the uniforms with labels bearing their school's name.
Secondly, wearing uniforms helps students feel equal in many ways, whether they arc rich or poor.
Finally, wearing uniforms is practical. You don’t have to think of what to wear every day.
Therefore, students in secondary schools should wear uniforms.
