PolyU considers it necessary to call for joint actions from everyone to make the world more inclusive, peaceful and sustainable. The University’s Institute of Textiles and Clothing (ITC) and the Office of Service-Learning (OSL) have recently collaborated with the New Life Psychiatric Rehabilitation Association in a meaningful Service-Learning Project in fashion design. This project aims at training students to adopt fashion creativity and expressive textile arts as a caring medium and to help service participants who are Person-in-Recovery to enhance their self-confidence. In groups, students and the service participants cooperated to design unique fashion prototypes and exhibited on the fashion show runway. A fashion show, named Laugh and Walk Together for a Better Future, was staged on campus to exhibit their deliverables and raised public awareness of building an inclusive and sustainable society successfully.
