Absolute elegance and sculptural fluidity: this black trouser dress by Yves Saint Laurent Rive Gauche in size 38 is the perfect embodiment of the couturier's revolutionary vision of women's dressing. With its long, streamlined silhouette, dropped sleeves and loose, almost theatrical cut, this piece subtly plays between evening gown and reinvented tuxedo. Its deep black fabric, with its supple, heavy fall, lends a natural grace to every movement. A rare and powerful creation, both sober and radical, true to the Saint Laurent spirit. In very good condition.
