In my opinion, students should wear casual clothes instead of wearing uniform at school.
First, It makes students feel more comfortable than wearing uniform. They can wear which clothes they want and it helps students have better studying mood.
Second, It also gives students freedom of choice. Wearing favorite clothes as well as casual clothes makes students feel self-confident.
Third, when students wear casual clothes, the school is more colorful and lively.
In conclusion, students should wear casual clothes.
