Le Smoking is a women's tuxedo suit created in 1966 by couturier Yves Saint Laurent.
[1] The first suit of its kind to earn attention in the fashion world and in popular culture, it was influenced by the androgynous personal style of Saint Laurent model and muse Danielle Luquet de Saint Germain,[2][3] as well as the evening dress of artist Niki de Saint-Phalle.
The waistline of the blouse was narrowed to show the body shape, and the pants were adjusted to help elongate the leg.
It pioneered long, minimalist, androgynous styles for women, as well as the use of power suits and the pantsuit in modern-day society.
[7] Saint Laurent was seen by many as having empowered women by giving them the option to wear clothes that were normally worn by men with influence and power.
