Technology advances have lifted us to a new standard of living unprecedented. But they've also created societies defined by wasteful consumption and unsustainability. Fashion industry is at the center of this concern, and have intensified by the prevalent of fast fashion in recent years. We need right now a new approach to balance the needs of fashion and nature environment beyond existing practice like eco design or recycling. It's a big challenge since fashion industry is based on a model of ever-increasing consumption, but sustainability is pursuing nature preservation. To realize sustainable fashion, we need to generate new ideas through design thinking on how to produce fashion with a sense of ethics, and socially responsible manner. Here a radical new mindset among designers and manufacturers is needed to attain sustainable improvements in the relationship between production and consumption. On the other hand, a compressive recognition of the impact of clothing consumption and fundamental shifts in consumer behavior are indispensable. Although this may be a difficult process with very slow progress, but is essential not only for fashion business but also our survival.
