Theatre and comics have a lot in common – both medias use not only text but also visual elements in order to tell stories and develop characters. For the comic-production of Im Spiegelsaal (In the Hall of Mirrors), based on Liv Strömquist, at the ZHdK, costumes were created made entirely of second-hand, leftover and waste material. The design process demonstrates how creative reuse works in costume design and contributes to SDG 12.5 with the goal of significantly reducing waste generation.
