Texas Republican Attorney General Ken Paxton opened an investigation into Shein, the popular online store for fast-fashion products, on Monday over possible unethical labor practices and unsafe products.

The investigation will determine whether Shein violates Texas law through its supply chain and manufacturing practices, use of toxic or hazardous materials, and possibly misleading information provided to consumers on product safety and ethical sourcing. The investigation will also examine the company’s data collection and privacy practices, which may pose risks to millions of consumers.
