To show a bit of Jackie O style, you needn’t forage for a vintage couture suit, pillbox, gloves and pearls — you’d likely look like you’re attending a “Mad Men” costume party. Instead, adapt a timeless look, as Onassis herself did. In a photo of 1970s night life, she’s the one wearing a classic little black dress amid a sea of earth tones. An online collection of her clothing from the John F. Kennedy Presidential Library and Museum shows a black Chanel suit with embroidered silk blouse, for example. It would look just as elegant today. Check out the Jackie O styled shoot coming to the Fall/Winter 2013 issue. Find your vintage style and channel your inner Jackie.
