This week we look at ethical fashion in the age of "direct-to-consumer" giants like China's Shein and Temu. Thanks to their business model based on ultra-fast design and production, consumers can purchase a new look at incredibly low prices. But at what cost for the environment and worker wellbeing? Charles Pellegrin talks to Kamila Boudova, a Paris-based slow fashion coach who helps her clients create ethical wardrobes. They discuss the challenges of wearing ethical clothes in an age of ultra-fast fashion.

Our China correspondent Yena Lee obtained access to a clothes manufacturing site that focuses solely on selling items on Temu. The platform has been described as "Amazon on steroids". Since launching two years ago it has exploded onto the global e-commerce scene, shipping to around 50 countries.
