In fact, you only need to wear props to participate in the program, and you don't need to dress up.

Many enterprises or institutions will hold small parties on New Year's Day to relax their employees. For employees who have already participated in the plan, they don't need to wear plan clothes. Before the party starts, there are usually many rehearsals, and some employees even keep in touch with the performance. After the performance, employees will go directly to their posts and will not stay backstage for too long, so it is ok to wear performance costumes. Unless there is a clear dress code during the performance, there is no need to prepare clothes.
