Loulou de la Falaise. Oh I wish I have a name like that. Must must go to Maison de Loulou when in Paris. She's the muse of Yves Saint Laurent for 3 decades, and the known inspiration for the notorious Le Smoking collection. Born to Maxime de la Falaise, a model for Elsa Schiaparelli and supposed food maven and cookbook author, LouLou was arguably born into fashion royalty.
