As a TV writer, I’d amassed designer gowns for various black-tie events. Once a friend who was shopping with me for an Emmy dress asked the saleswoman, “Don’t you have anything fabulous in the back?”—and she reappeared with a couture Christian Lacroix strapless, hand-beaded gown that had only just been delivered to the store. Sold!
