Book excerpt: The Psychology of Fashion offers an insightful introduction to the exciting and dynamic world of fashion in relation to human behaviour, from how clothing can affect our cognitive processes to the way retail environments manipulate consumer behaviour. The book explores how fashion design can impact healthy body image, how psychology can inform a more sustainable perspective on the production and disposal of clothing, and why we develop certain shopping behaviours. With fashion imagery ever present in the streets, press and media, The Psychology of Fashion shows how fashion and psychology can make a positive difference to our lives.
