The global plus size women's clothing market is projected to grow at a compound annual growth rate (CAGR) of 4.3% from 2023 to 2031.

The market is segmented by product type, age group, distribution channel, and region. The innerwear segment is expected to grow at the fastest CAGR during the forecast period, as there is a growing demand for comfortable and stylish innerwear for plus size women. 

The 25-45 years age group is the largest market segment, and is expected to maintain its dominance during the forecast period. Online channels are expected to be the fastest-growing distribution channel, as they offer a wider range of plus size clothing and convenient shopping options.

The Asia Pacific region is the largest market for plus size women's clothing, and is expected to maintain its dominance during the forecast period. This is due to the growing middle class in the region and the increasing awareness of fashion among plus size women.
