While performing in 1947 at Ciro's nightclub in Hollywood (billed as the "Anatomic Bomb"), St. Cyr was arrested by police and taken to court by a customer who considered her act lewd and lascivious. Represented by the infamous Hollywood attorney Jerry Giesler in court, St. Cyr insisted to the jury that her act was refined and elegant. As St. Cyr pointed out, what she did was slip off her dress, try on a hat, slip off her brassiere (there was another underneath), slip into a négligée. Then, undressing discreetly behind her maid, she stepped into a bubble bath, splashed around, and emerged, more or less dressed. After her appearance as a witness, as a newspaper account of the time put it, "The defense rested, as did everyone else." After just 80 minutes of deliberation by the jury, St. Cyr was acquitted.
