Green Initiatives does an interactive workshop on bringing sustainability to fashion. They say, "We welcome participation from individuals of all backgrounds - be it fashion designers, textile industry professionals, or simply consumers. We hope to turn this into an evening of learning + inspiration, where everyone can leave the event with more knowledge + tools to engage in eco-responsible fashion! It’s time to rethink textile waste!" They ask you to bring your unwanted clothes to swap and for a discount, otherwise it's 100rmb to join. Starts at 6.30pm. Details here.
