The Milan Fashion Week, one of the world’s four top haute couture spots, has an unexpected and green start this year. A Greenpeace activist walks along a 12-meter long ‘vertical catwalk’ on the façade of the splendid Sforzesco Castle, greeting participants and journalists as the show opened its doors. The "green gauntlet” is thrown down to 15 luxury fashion brands as part of Greenpeace Italy’s "Fashion Duel." Greenpeace is demanding brands engage in the smartest trend: beautiful clothes untainted by forest destruction and toxic pollution of our water’s resources.
