This isn’t just another sartorial choice—it’s a nod to a long history of feminine power dressing. Originally democratised for the English elite in the 1890s, the tuxedo jacket became an emblem of male style. By the early 20th century, rebellious women like Renée Vivien began borrowing the piece from men’s wardrobes, paving the way for its entry into female fashion. Marlène Dietrich popularized the look on-screen in the 1930 film Morocco, and the women’s tuxedo gained traction from the 1960s, both on runways and in the streets.

It was Yves Saint Laurent who elevated the tuxedo jacket to a symbol of feminine power in his 1966 fall-winter collection. Despite initial skepticism, his groundbreaking design resonated with women seeking bold, modern style, and the tuxedo jacket became a staple. Helmut Newton immortalised it in his 1975 photograph, and Yves Saint Laurent paid homage to this piece again during his 2002 retrospective show, cementing its place in fashion history.
