This document summarizes a study on fast fashion, sustainability, and luxury brands. The researchers interviewed young consumers in Hong Kong and Canada about their perceptions of fast fashion, sustainability, and luxury goods. They found that while consumers are concerned about the environment, sustainability is not commonly associated with fashion. However, luxury brands that emphasize quality and craftsmanship may be able to unite fashion and sustainability. The rapid production cycles of fast fashion lead to unsustainability, but fill the desire for new styles and identities.
