It may seem odd when an industry that relies on seasonal trends and consumption talks about 'going green'. But Lucy Siegle has had a keen eye to the fashion industry and has been charting efforts to improve things. She heads to La Scala in Milan for the very first Green Carpet Fashion Awards, rubbing shoulders with Gisele, Anna Wintour and Giorgio Armani, where the big names in the industry are gathering to respond to calls for greener fashion. Is this the sign of new era starting from the top? Lucy heads back to the UK, where the 18-35 year olds are leading the charge in wanting more sustainable fashion. She reveals how we shop and looks at which fabrics could potentially challenge cotton and polyester and what it would take for them to be a mainstay in our wardrobes. For the fashion loving consumer who's not ready for a lecture, we reveal the new developments from retail and 'change disruptors' and ask if the 'lucky pants' theory could change our behaviour.
