Expressive Wearable explores clothing as a communication tool. This project imagines a scenario in which clothing expresses the wearer’s attitude directly without the concern of adhering to social conventions. More broadly, the project explores how people might playfully use wearables that move and gesture, what the aesthetics of these will be, and how wearables might interact with each other in group situations. This project speaks up in silence, using ambiguity as a guidance to explore a seemingly impromptu interaction meanwhile delivering meaningful message accurately and expressively. It provokes social conventions by speculating on the complexity of human psychology behaviors.
