British activist Sara Arnold and Dutch fashion scholar/activist Sandra Niessen explain their vision for "a radical defashion future" driven by degrowth, decolonization, and commoning. As two leaders of Fashion Act Now, they are part of a growing network of dissident fashionistas trying to make the global clothing industry more ecologically responsible, relocalized, and responsive to climate change. They argue that the fashion industry needs a serious economic and cultural makeover to curb its colossal waste and energy use, and allow a rich pluriverse of clothing cultures to flourish.
