In China's huge market domestic demand has become the main source of power for the steady growth of the domestic apparel industry, with the continuous increase in per capita disposable income and social openness continues to improve, whether urban or rural residents, for clothing consumption is still growing.

With the advent of the big data era, people are getting closer and closer to the essence of things, outlawing redundant procedures, and pointing directly to the core value of things. As a result, the channel hierarchy in the apparel industry has been extremely compressed, and the chain between the factory and the consumer will be shortened indefinitely.

The growing number of overweight and obese women has led to an increase in demand for plus-size women's clothing, who not only want clothing to fit their body type, but also to conform to the latest fashion trends. As a result, plus-size women's apparel has become the fastest growing sub-segment under women's apparel.

Based on different product types, plus-size women's apparel can be categorized into tops, T-shirts, dresses, underwear and pants. Of these, underwear will be the fastest growing during the forecast period.
