Civil servants are not allowed to wear professional clothes during interviews, mainly referring to work uniforms, such as bank and court uniforms. As long as you don't wear forbidden clothes during the interview, what others have worn can still be worn, as long as it suits you.

Boys' suits and coats should be black, navy blue and gray, and the length of the coat should cover the buttocks. The color of trousers should be the same as that of the coat, mainly dark or gray, and the length of trousers should cover three quarters of the heel in an upright state. Girls' interview clothes are generally suitable for suits and dresses. Black and navy blue coats and trousers with light-colored (white and beige) shirts are the best choice.
