Skirts and clothes are separate, and skirts are bust.
It is very difficult for 56 ethnic groups to choose a uniform and representative costume. There is a long-standing debate about China's national costume on the Internet.
If LZ refers to the national costumes of the Han nationality, I personally think it is not appropriate. The national costumes of the Han nationality died out under the coercion of the Qing Dynasty. At that time, as the main body of society, men were wearing Manchu costumes, so women's costumes naturally changed. In the Republic of China, just like the pictures posted by LZ, there was no Han nationality feature except the clothes above and the skirts below.
The national costume of our Han nationality can be Hanfu, which was our costume before the Qing Dynasty.
