To kick off June, our month dedicated to "Men," let's take a look back at that classic menswear staple, the tuxedo, given a feminine touch by Yves Saint Laurent some five decades ago: Along with the bikini, the wrap-dress and the tranny heel, Le Smoking is the greatest sartorial invention of the past 50 years. And it would behoove every woman to have one in her repertoire. Created by Yves Saint Laurent in 1966, Le Smoking forever changed the way women dressed by simply giving them a tux all their own. It was further immortalized in a series of photos by Helmut Newton in the 70s and when Saint Laurent muses like Bianca Jagger, Betty Catroux and Catherine Deneuve made YSL's lady-tux the "It" garment of the "It" girl. Now 400 years later the trend is still going strong.
