As a starting point, this paper considers a compelling idea concerning fashion and sustainable HCI - -rather than attempt to thwart fashion, or exhort people not to engage in fashion-related behavior, instead, based on a deeper understanding of the complexity of fashion, utilize this concept to design products and services so as to resonate with those dimensions of fashion that are most compatible with sustainability. Our ultimate vision is to provide mechanisms to allow designers to use fashion as a positive force for sustainable design, especially in the context of HCI and interaction design. As a step along the path between this starting point and our ultimate vision, this paper describes some related literature and thoughts about methods, reports on a collection of interviews and emergent insights, and several general design implications which link fashion positively to sustainable practices and futures. Moreover, we hope to inspire others to contribute to this idea and its potential for sustainable HCI. © 2012 Authors.
