By exploring the notional interior of the deco dandy, this chapter challenges the extant scholarship that has long positioned the female consumer and woman decorator as the exclusive arbiters of national, industrial and design debates in the post-war period. The point of entry here is Monsieur magazine, interrogated and situated within the larger cultural history of interior design that emerged prior to and after the war, when a crusade for purism by modernists like Swiss-born architect Le Corbusier was being waged leading up to the Exposition des Arts Décoratifs et Industriels Modernes of 1925. By examining selective and unique case studies the chapter also explores interior spaces associated with actor Jaque Catelain and modern ballet dancer Jean Börlin and the impact physique culture was having on the development of the French interior. Catelain and Börlin were not simply performers in the literal sense, but cultural forces both celebrated and feared that help us to think through the ways cinema and dance in general, and their bodies in particular, might be used to explore other forms of cultural production, namely interior design and furniture.
