In the 1966, YSL introduced a Tuxedo to women, called "Le Smokin", inspired by men's smoking coats, the texture of silk, so that women can be in social situations, streets, wearing "Le smokin" smoking without getting full of soot. "Le Smokin" means that women will be more involved in social activities, move around at any time without restriction, participate in society and even light up a cigarette on the street at night and enjoy their own time.
