It is best to wear clothes of the same color from top to bottom. Tutu skirts are the most commonly used dresses. If you don’t want to be too formal, then wear a long skirt, not too Chinese style. Cheongsam style is not good, preferably A The kind with font hem. The folk music side should be more traditional Chinese clothing. There should be a clear contrast on the Bel Canto side.
On such occasions, regardless of height, girls must wear high heels, but do not wear formal high heels.
