It should come as little surprise that Amazon was the top US shopping app in 2021, downloaded 40.0 million times that year. More remarkable is Shein’s leap to the No. 2 spot, up from seventh place in 2020. The Chinese fashion giant had 32.0 million US downloads under its belt in 2021, 68% more than the year prior.

Beyond the chart: In the worldwide rankings, Shein overtook Amazon last year, though Southeast Asia’s Shopee outperformed them both. Still, Shein has dazzled US consumers with its revolving door of clothing and accessories, making up 28% of the country’s fast-fashion market, per Earnest Research.
