COS style is becoming more and more popular now. I like to wear COS clothes to keep up with the trend of the times and imitate anime characters. But at school, I don't think it's appropriate. Schools are public places. If teachers see them, they will have a bad impression on them. It is recommended to go out to play, or wear nothing in the dormitory. But don't wear it at home. My parents don't know about it. They think their clothes are sloppy and they are social youths. If parents find wearing COS clothes, it is easy to cause conflicts.
I have a friend who loves COS style, so she often dyes her hair and wears strange clothes. At first, her parents opposed her and thought it was neither fish nor fowl. But she insisted on wearing it and patiently persuaded her parents that wearing COS was only for better friendship and wanted to be a model in the future. Later, parents looked at their daughter's future direction and thought it was good to be a model and show their beauty. So she reluctantly agreed, so as not to hurt her self-esteem.
In fact, when you are caught accidentally wearing COS clothes, you can patiently explain to your parents, convince them and let them agree. If it really doesn't work, then simply give up and concentrate on your studies. Just for fun.
