There are four main product categories for the apparel and footwear market: womenswear, menswear, sportswear, and childrenswear. Womenswear was the bestselling apparel category in the world as of 2017, with sales of about 643 billion U.S. dollars. The United States alone generated 121 billion U.S. dollars in womenswear sales, and about 90 billion dollars in menswear sales. Another important category with a high level of growth is the sports apparel market, which grew in value from 118 billion euros in 2015 to about 154 billion in 2016. There is also a thriving market for pre-owned, or second-hand clothing through vintage stores, thrift store, or consignment stores. This apparel resale market value increased from 18 billion U.S. dollars to 20 billion dollars between 2016 and 2017. Denim, a classic staple of a casual wardrobe, is only getting more popular across every type of clothing item.
Although there are countless apparel retailers across the world, both big and small, the biggest companies control the majority of the market. As of 2017, the three top selling apparel and footwear retailers were TJX Companies, Inditex, and H&M. In terms of casual apparel, The Gap, Inc. was the top selling retailer, with sales of about 16.2 billion U.S. dollars. Luxury clothing, on the other hand, was led in sales by LVMH Moet Hennessy Louis Vuitton S.E., an enormous French luxury goods conglomerate.
In terms of individual brands, the sportswear brand Nike took up a 2.8 percent share of the market in 2017, more than any other brand. As of 2018, some of the other most valuable brands in the world included H&M, Zara, Adidas, and Hermes.
