There are many kinds of conjoined skirts, which can be basically divided into long skirts and short skirts. A long skirt is a skirt that hangs below the knee and becomes a whole. A short skirt is a skirt that usually reaches the waist and wraps the hips. One-piece skirt has been one of the most commonly used clothes since ancient times. In ancient China, the corset was connected with the lower garment, and the dresses in ancient Egypt, ancient Greece and the two river basins all had the basic shape of the dress, which could be worn by both men and women, but there were differences in specific details. In Europe before the First World War, the mainstream of women's clothing was dress, which was used as a formal dress to attend various ceremonial occasions. After the First World War, because more and more women participated in social work, the types of clothes were no longer limited to dresses, but it was still an important dress. As dresses, most of them still appear in the form of dresses. With the development of the times, there are more and more kinds of dresses. In the pre-Qin period in China, people generally wore heavy clothes, which can be regarded as a variation of formal dresses. High-quality sundresses and skirts in Yuan Dynasty are similar to pleated skirts and dresses. However, in general, the styles of dresses were relatively rare in ancient China. In modern times, western-style dresses were introduced into China and became one of the clothes that people in China often wear.
