1, usually wear three sets of clothes, such as three-day pants and three T-shirts. Buy a few pairs of shoes if you have money. This is not mandatory.
2. There are clothes to wear during sports, such as basketball clothes and football clothes.
Don't wear sleeveless clothes, such as basketball clothes, and don't wear slippers in class. For example, you can choose to wear slippers in rainy days.
That's all I gave. I will make my own decision when I get to school.
