Although it has not been thoroughly studied, the usual "black dress" concerts are mainly confined to the category of "serious music", such as symphonies, chamber music and some vocal concerts. "Black" concerts mainly take place in the west, with black representing solemnity. Most people wear black dresses on formal occasions, and because more important parties take place at night, they are also called "evening dresses" and "evening dresses". Of course, sometimes women will wear white clothes with men's black, which shows the difference between men and women, and also shows the nobility and purity of women. The more relaxed concerts can be displayed in white or fancy 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 China people on dress color.
