Jackie Kennedy was a certified style icon even before she officially took on the role of first lady, inspiring countless copycats and setting major trends every time she stepped out in a new monochromatic ensemble, Chanel suit, or pillbox hat. But her reign as Queen of Camelot was just the beginning for Jackie O, as she became known after her marriage to Aristotle Onassis in 1968. Naturally, the former first lady ushered in her new era with a new look, this one centered around billowy maxi dresses and menswear-inspired suits. And, of course, she debuted a new signature accessory: oversized sunglasses. In the later 70s, widowed once again, Jackie put the focus on her career as a book editor, and adopted a businesswoman-about-town style to match. Today, on what would have been her 90th birthday, Onassis's status as Commander-in-Chief of Style remains unrivaled—despite the current president's insistence that the title has now been taken up by Melania Trump. Here, a look back at how Onassis made her mark on fashion and influenced generations of women to come.
