Fashion Revolution Week, a sustainable fashion event and movement .Fashion Revolution, marks a week of campaigns, protests and online information sharing to demand greater transparency in the fashion supply chain. Co-founded by Carry Somers and Orsola de Castr, the movement publishes a Fashion Transparency Index each year, detailing some of brands which are leading the way on transparency, which brands are improving, and where there is more work to be done. This year, the fifth Index will be published, the biggest to date, including details of 250 of the world’s biggest fashion brands and retailers.
