Through the story of her research, encounters and experiences, Claire Latour, an influencer, explores the underside of ultra fast fashion giant: Shein. True ecological cost, quality and toxicity of clothing, sales techniques, greenwashing or even the reasons for an ultra-low price, this unprecedented survey leads him to question his way of consuming… but also to influence. In just five years, the Chinese brand has succeeded in dethroning Zara, H&M and other fast fashion giants, who watch, stunned, the meteoric rise of this new rival. Shein goes even further than its predecessors by amplifying the strategies that made them successful: a constantly evolving catalog, prices that defy all competition, and communication powered by thousands of influencers. A few months after the first media scandals, Claire Latour announced the end of her partnership with the brand. Today, Claire gives us the story of a one-year investigation on this Chinese mastodon, revealing behind the scenes of a brand that continues to grow: between toxic clothing, overproduction, poor quality and catastrophic ecological assessment, Shein smashes all the records of ultra fast fashion. Moreover, the survey also addresses the precarious working conditions imposed on Chinese employees, often subject to excessive hours and derisory salaries to meet the unbridled demand of this constantly expanding company.
