1. When I go to school I prefer formal clothes, like shirt and dark pants. But when I go out with my friends I like to feel comfortable, so it's usually sweatpants, or jeans with colorful t-shirts, or blouses when it's cold outside.
2. At school I want to feel elegant, and I think I can show my respect to school and education through the way I am dressed. With friends I just want to feel comfortable, we also like going outside and do sport activities together, so it doesn't make sense to dress elegant.
