This chapter explores the invasive action of contemporary luxury production and consumption, by using fashion as a means with which to more closely observe its characteristic stages. The basic plain white T-shirt, ubiquitous, instantly familiar and apparently simple, has provided a fertile vestimentary culture in which luxury's recent diversification and adaptation can be detected. A garment as democratic, modest, and undistinguished would seem at first glance an unlikely target for luxury's conquest, and yet the chapter argues that it is precisely because of its humble and unpretentious origins that luxury finds in it its ideal sartorial colony. What was once a utilitarian, basic item of clothing that served specific sanitary, economic and thermal functions has been completely transformed into a prohibitively expensive and, it could be argued, functionless garment, despite the often employed qualification of those same items as ‘basic’.
