On my way home after school, I see many students wearing school uniforms. I sometimes think back to with my school days. I wore a uniform from middle school to high school. Once many students did not wear the same clothes, but after a few years they began to wear them again in most schools. Why did they start wearing school uniforms again? I think students can act more responsibly if they wear a school uniform. But though some students enter the same school, their uniforms look different from one another. I'd like to write about the reasons they are wearing different uniforms.
　　　 Firstly, students can study harder if they wear school uniforms according to the rules. These clothes were produced to be suitable for the body and behavior of students. They are very convenient and efficient. We can sometimes see a school uniform which we can't recognize as a school uniform on the street. A few months ago, I saw a boy student. When I saw him at first, I didn't know what he was wearing. When I looked closer, I saw that he was wearing an altered school uniform. I laughed because his pants looked like he was wearing stockings. Many students change their school uniforms according to their will. In my opinion, however, they don't express their individuality; they only imitate the pictures of adults. These clothes look pretty, but they are not convenient. These things don't function as school uniforms which can help students study effectively.
　　　 Secondly, if students modify their school uniforms, they do not look like students. Their school uniforms imitate the clothes of adults, and also they try to imitate other accessories of adults--rings, hairpins, etc. They imitate only the images of adults uniform from head to toe. They wear school uniforms with high-heeled shoes and strange bags like adults. We can see many kinds of school uniforms--mini skirts, uniforms that cling to the body, etc.
　　　 Finally, students can't feel a common consciousness if they wear altered uniforms. A school uniform reminds students that they are students and that they are part of a group. If students wear a school uniform, they can't feel the difference between rich and poor. At that time, they are all students who go to school to learn knowledge. But if they alter their uniforms, this merit will disappear. Though they wear a school uniform, they can't feel common consciousness because their uniforms differ from one another. They can have preconceived ideas about other students because of their clothes, so they can't make friends with other people easily.
　　　 It is important to wear a unchanged school uniform. When uniform don't fit well, student can repair their clothes a little. But I think it is not necessary for students to make their uniforms look like the clothes of adults. If a girl's skirt is very short and tight, for example, it is not very convenient. It is hard for students to concentrate on studying. I heard from my friend who did not wear a uniform when she was a student that she always was worried about what clothes to wear on the next morning. When students wearing uniforms try to drink and smoke, adults can forbid their behavior of out of school. Students can learn from all adults. All students must remember they are students who are studying.
