In the early 1960's Oleg Cassini designed Jacqueline Kennedy's entire wardrobe as first lady. Today supermodel Jessica Stam won't leave home without the designer's trademark sunglasses. This is a man who has left his mark. Cassini died two years ago, leaving behind a legacy of style that made women feel smart, natural and beautiful. From his iconic pillbox hats to his geometric shift dresses, Cassini knew exactly how to make a woman feel fashionable. Seeking inspiration from the work of Hubert de Givenchy (think Audrey Hepburn in Sabrina) Cassini always put his love for quality and uniqueness first. His vision was reflected through the way he turned himself out, even in the final year of his life. When stopped on the street in 2006 by the maker's of New York Magazine's street fashion book, Look Book, Cassini proudly stated, 'I can afford to have the most stylish clothes because I am slim...like that of a very athletic, young guy.'Seen left: The always debonair Oleg Cassini makes Jacquie O swoon.
