Fashion is a social phenomenon that can only be defined and understood using a trans-disciplinary approach. A number of questions arise: which special perceptive abilities does a creator of fashion have to have? To which extent are smart clothes integrated in everyday fashion? How does architecture react to the requirements of fashion? Can a costume designer design clothes successfully and vice versa? These and many other questions are addressed as well as the problems involved fashion design training or fashion designers responsibilities in terms of sustainability. This publication is based on the discourse that has been under way at the Vienna School of Fashion as a cultural design phenomenon between international representatives from the fields of art, fashion, architecture, science and business. The fashion phenomenon is followed from different perspectives and with thematic contributions.
