Who made my clothes? Untangling the fashion supply chain, model Charli Howard gets a first-hand account of what it takes to stitch the western wardrobe from Bangladeshi garment-worker-turned-activist Kalpona Akter. Kalpona shares her journey from being a child working on a factory floor to becoming a frontline campaigner for jobs with dignity in the garment factories of Bangladesh and beyond. How can we be sure that £2 T-shirt didn't cost someone's livelihood - or even their life - as in the case of the Rana Plaza factory collapse of 2013? Well, now there's an app for that - sort of. Good On You co-founder Sandra Capponi explains how the app rates fashion brands on their impact on people, planet and animals. The app aims to empower shoppers to make ethical choices, while incentivising the industry to do better. Presenter: Charli Howard Producer: Kirsty McQuire Editor: Rebecca Stratford
