That depends on how common basketball is. An ordinary 100 yuan will do. If you want something ordinary, there are dozens. There will be hundreds counting down from ten rubber basketballs. I've seen the most common basketball clothes in their twenties and thirties, and the better ones are about 120 yuan. Customized clothes like those worn by people in the NBA, such as Kobe James, can buy a suit in about fifty or sixty years, but I don't think it matters if you wear ten or eight pieces. The key is to be worthy of yourself.
