In London during the Second World War, jumpsuits—already the playsuits and worksuits of the 20th century, which adopted them from the child’s jumper of the 19th century—were called Siren Suits, not for their allure, but for the speed with which one could leap into them in the event of a nighttime air raid alert. As catsuits (that is, with their legs changed to tights), jumpsuits are Siren Suits of a different order worn, most notably, by the avenging Mrs. Emma Peel (Diana Rigg, Uma Thurman) and by Catwoman herself (Julie Newmar, Eartha Kitt, Michelle Pfeiffer).
