Shein is the world's leading online clothing retailer. In 2022, the online platform was the first place to buy clothing for 15-24 year olds in France.

In 2021, its sales jumped 60%, propelling its turnover to $ 16 billion, according to Bloomberg. The firm is regularly accused of profiting from the exploitation of members of the Uighur Muslim minority in cotton fields and workshops in the Xinjiang region of western China. It is also singled out for having become a symbol of "ultra fast fashion", or the rapid renewal of collections at very low prices.
