What are the requirements for applying for COS?

You don't need money to join the league. If you want to apply, you should have a look with the group leader (it is best to wear COS to see the group leader), but if you want to participate in some activities such as fan parties, you should pay for tickets yourself. Anyway, all activities that need money are AA clubs, which are generally online exchanges. There will be face-to-face exchanges, and members will also make some suggestions, such as which tailor is good at craftsmanship and which store sells props. Generally, for example, the clothes in Lu Luxiu can be ordered at 300~800. The price is related to the material, but COS shows will be organized in various parks every 2-3 months, and the regular fan meeting every year (I don't know when, Guangzhou, Shanghai, three times a year, CC4 in May this year,11+1CC5, August and August summer festivals) has nothing to do with study. POSE can practice for half an hour every day, but clothes should be maintained, polished and photographed at least once a month.
