'This is a major book and a highly significant contribution to our understanding of how specific features of the fashion economy operate. Drawing on fascinating field work in a well-known department store and also in fashion model agencies, Entwistle uses the new sociology of markets and of actor networks to analyse the calculative practices which underpin the production of fashion worlds and their objects. This book has great originality and depth, and will be used across a range of academic disciplines.'Angela McRobbie, Goldsmiths, University of London
