In June, the global fast-fashion retailer Shein treated a group of social media influencers to an all-expenses paid trip to Guangzhou, a city in southeast China. Glamorous at the onset, Shein took these “brand ambassadors” — individuals paid to endorse the company’s products — on tours of the company’s “aboveboard” factories. Soon after, the individuals shared raving reviews of the working conditions, suggesting no signs of maltreatment or forced labor.
