For about two decades towards the end of the Victorian era, in the 1870s and 1880s, a large bustle-enhanced bottom was the height of fashion. In this episode we explore how it’s connected to today’s big booty craze. We look at the bustle’s history with a curator fascinated by old undergarments; consider the various theories about its popularity with the author Heather Radke; and then hone in the tragic story of Sarah Baartman. The bustle may be old-fashioned, but it still has a lot to tell us about race, sex, power and how much people know, or let themselves know, about what they put on everyday. We hear from Heather Radke, author of Butts: A Backstory, as well as Kristina Haughland, Janell Hobson, Pamela Scully, and Maria Garcia.  Special thanks to Wesley Stevens and Daisy Rosario.
