This book will discuss the fashion industry's corporate communication of sustainable apparel to engage people between the ages of 25-35. The author studied U.S. Millennial's attitudes and opinions, and concluded that members of this demographic are willing to change their behaviors if they know they will solve an issue or support a social cause. The findings of this publication, serve as a communications guide to fashion companies, by providing the insights needed to effectively communicate with their target audience. The study could also make other fashion companies realize the importance sustainable apparel has to Millennials. Hence, sustainable fashion companies need to communicate the negative environmental and social impact caused by the fashion industry, along with sustainable fashion concepts, and practices in order to engage the target audience. Fashion companies should take into consideration the importance of transparency when communicating with this audience.
