Roger Vadim’s Barbarella (1968) looms large in popular culture. Disguised under its sartorial splendour, the film’s narrative clearly negotiates social anxieties of the late 1960s. Similarly, the production design of the film incorporates contemporary elements from art, architecture and fashion. Arguably, these elements of style have played a key role in catapulting the film to its cult status. Spanish designer Paco Rabanne is frequently, albeit erroneously, credited for the creation of Jane Fonda’s onscreen parade of highly-stylized costumes in the film. In fact, the man responsible for creating fashion in the diegetic year 40,000 was French costume designer Jacques Fonteray. Rabanne’s involvement in the film was limited to the creation of one costume. Based on archival research conducted in France and the United States of America, this article explores the role of Jacques Fonteray in the creation of the film’s costumes while simultaneously debunking the popular misconception regarding Paco Rabanne’s influence on the film’s overall aesthetics.
