Designed by artist Adolphe Mouron Cassandre in 1961 whilst Yves was at the helm, the Cassandre logo has been central to the French fashion powerhouse for over four decades and Saint Laurent continues to show it off at any opportunity. We think you should too. The interlocked logo forms this brass brooch, which has a crocodile texture and an antique finish, adding a touch of Parisian luxe to any outfit.
