News in Brief: New York City, World's Costliest Dress. A $100,000 gown covered with 100,000 pearls and weighing 30 pounds, is modeled by film actress Gloria Swanson, during special charity showing for the Damon Runyon Fund for Cancer Research. Gloria is escorted by two police officers. She shows her lavish dress to a small group of guests and shows her pearl jewelry to the camera. Gloria lifts the pearl-studded skirt of the dress, then flexes one arm, making clear that the bejeweled outfit is heavy to lift.
