Fashion has considerable environmental impacts and social justice problems. This chapter discusses fashion in the context of sustainability from three different viewpoints: social, environmental and economic, i.e., from the viewpoints of people, the planet and profit. Previous ethical discussions have focused on the social aspect, from the viewpoint of working conditions in the textile and fashion field (labour rights) and later, on the environmental impacts in this industrial field. It is time to expand the discussion in order to understand the ethical side of fashion from the aspects of value, justice and responsibility.
