Through a variety of archival documents, artefacts, illustrations, and references to primary and secondary literature, On the Job explores the changing styles, business practices, and lived experiences of the people who make, sell, and wear service-industry uniforms in the United States. It highlights how the uniform business is distinct from the fashion business, including how manufacturing developed outside of the typical fashion hubs such as New York City; and gives attention to the ways that various types of employers (small business, corporate, government and others) differ in their ambitions and regulations surrounding uniforms. On the Job sheds new light on an understudied yet important field of dress and clothing within everyday life, and is an essential addition to any fashion historian’s library, appealing to all those interested in material culture, the service industry, heritage and history.
