Although it has not been thoroughly studied, the usual "black dress" concerts are mainly limited to the category of "serious music", such as symphony, chamber music and some vocal concerts. "Black" concerts are mainly held in the West, and black stands for solemnity. Most people wear black dresses on formal occasions. Because more important parties are held in the evening, they are also called "evening dresses" and "evening dresses". Of course, sometimes women wear white clothes with men's black, which shows the difference between men and women, and also shows the nobility and purity of women. Easier concerts can be displayed in white or gaudy clothes, which fully embodies the randomness and freedom of the concert nature. China's concert dress is mainly in red tone, which highlights the festive concept of dress color in China.
