Yves Saint Laurent

If fashion had a royal rumble, Yves Saint Laurent would be the effortlessly chic gladiator armed with a smoking jacket and a power suit. Talk about setting the bar high! This guy turned tuxedos into women’s wear and made it look like a walk in the park. Fans? More like cult followers. They'd probably wear a burlap sack if it had the YSL logo. Struggling because you can't afford a vintage Mondrian dress? Join the club. YSL isn’t just a label, it’s a lifestyle, and in the 'Greatest Fashion Designers of All Time' he’s basically the couture king.
