YSL couture gowns were an ode to the female form. These dresses, with a nod to the sculptor Lalanne, were displayed at Yves' 40th anniversary show. YSL was a fervent art collector and loved to pay hommage to his favourite artists in his designs, creating collections inspired by Picasso, Mondrian, Matisse and Goya. Travel was also a major inspiration, as can be seen from African and Russian influences in his work.
