Book excerpt: The book Fashion Business and Digital Transformation overviews the fashion industry and the key technologies that are changing the Retail fashion supply chain. We look at technologies that affect the environment, through artificial intelligence, virtual reality, augmented reality, digital fashion design, 3D textiles, and blockchain. We study how ideas like "retailtainment", "gamification", and e-commerce affect both the retailer and the customer. You'll also learn about important retailing trends, including global buying and sourcing, omnichannel retailing, online retailing, mobile technologies, and social media effects through the case studies.
