Indigo blue calico was a frequently used cotton dress material in areas south of the lower reaches of the Yangtze River. It uses indigo to paint on cotton woven by local rural people themselves. Such clothing was widely used in people's daily lives.

The cloth in the picture is a collection by Shanghai Printed Calico Museum. It has a lot of patterns, such as peony, peach, etc. It is a typical wear for local rural women.

As time goes by, some young women and foreigners tend to use it as a decoration in their houses.
