Before noticing this tribute in the Fashion pages of the Times, I wasn't aware that C.Z. Guest had died last weekend. C.Z. was one of those figures whom I found inexplicably fascinating, probably for the same reason that I occasionally browse the Times wedding announcements: she was a woman famous for little more than being rich, stylish, and beautiful, friend of Truman Capote, horsewoman, New York society hostess, former "glamour girl of the Massachusetts north shore." Hemingway was the best man at her wedding. Even if you have no particular affection for the idle rich, it's hard to dislike anyone who could inspire tributes like this: "She could be unbelievably funny without realizing it," Oscar de la Renta said. "She assumed, for instance, that everybody had a pony."
