Lee Radziwill, Jacqueline Kennedy’s younger sister, is one of the chicest style icons there is. Her glamour is effortless, and her lifestyle, well, simply glamorous — as evidenced in the new book from Assouline, Lee. In it, you’ll get an intimate look into her jet-set lifestyle and circle of beau-monde friends, including Andy Warhol, Truman Capote, Rudolf Nureyev and Giorgio Armani. Check out the slideshow above for a preview.
