How to treat college roommates borrowing clothes to wear?

Roommates often borrow clothes from me because I have a lot of basketball clothes. When he wants to play basketball, he will borrow my basketball suit. At first, I would lend it to him, but he always lent it to me, and I would have some dissatisfaction, because my clothes were worn by others, which made me feel very uncomfortable, so I explained this to him. I said that everyone has his own clothes, so you don't need to borrow my clothes in the future.
