This book, produced in close collaboration with the Yves Saint Laurent museums in Paris and Marrakesh, examines how flowers served as the designer’s muse throughout his life and work. Flowers in every form inspired fashion designer Yves Saint Laurent, serving as a leitmotif in his work. His passion for plants manifested itself in countless patterns and techniques, and he adorned women in floral appliqués, prints, and embroideries. From a thousand and one rose buds to sprigs of lily of the valley, from an avalanche of bougainvillea to delicate poppy blooms, and from sheaves of wheat to majestic lilies, nature was an essential part of his visual palette. Through the discerning eyes of Olivier Saillard, this veritable garden of Yves Saint Laurent’s designs—culled from a broad range of styles—metamorphoses into a bouquet of flowering silhouettes. Under the direction of Elsa Janssen and Alexis Sornin, essays from Emanuele Coccia, Marc Jeanson, and Serena Bucalo Mussely explore, respectively, the symbolism of flowers, characteristics of his recurring prints, and the designer’s signature use of flora in accessories. This book accompanies exhibitions at the Yves Saint Laurent museums in Paris and Marrakesh in 2024 and 2025.
