A model wears a three-piece suit designed by Yves Saint Laurent. France, 1967. He reworked the rules of fashion by putting women into elegant pantsuits that came to define how modern women dressed. By putting a woman in a man’s tuxedo, he changed fashion forever, in a style that was never dated. “Chanel gave liberation of the body to women,” said Pierre Berge, Laurent’s longtime business partner, “and Saint Laurent gave power to women with the men’s clothes.”
