Matching her provocative performance Marilyn wore a skin-colored silk dress with 2,500 rhinestones by Jean Louis (†89), which was sewn together directly on her body at the time. Since the dress was so tight, Marilyn was not able to wear any underwear. "It was just the silk dress and the crystals," Martin Nolan, managing director of Julien's auction house, told the Irish Times.
