SHEIN, a fast fashion e-commerce app, has reportedly overtaken Amazon as the most downloaded shopping app on iOS and Android platforms in the U.S., according to data from App Annie and Sensor Tower.
The China-based startup has kept an unusually low profile and tried to keep itself out of the media, despite being valued at more than $15 billion.
The app, which China-focused Internet analyst Matthew Brennan has called "the TikTok for e-commerce", is also made in China.
