Iconic in every sense of the word, Yves Saint Laurent's 'Le Smoking' shook 1960s Paris. The bold, menswear-inspired tuxedo suit maintains its relevance in Saint Laurent’s long-line black grain de poudre wool version. It's cut with sharp shoulders and cropped sleeves – to frame a classic watch or statement cuff – and finished with black satin peak lapels and a singular button fastening.
