Yves Saint Laurent wrote his only known comic book La Vilaine Lulu, Natsy Lulu, the tale of a 10 year-old girl with mischief and perversion on her mind, while at Christian Dior. On Françoise Sagan’s urging, Lulu was published in 1967 - the year of the three-piece pant suits, short smoking and safari dresses. The year Saint Laurent met Betty Catroux.
In the book preface, Saint Laurent distances himself from his subject. Lulu is, rather, one of his collaborators at Dior:
Often, after six o’clock, one of the designers at Christian Dior would get dressed up in the clothes. One evening, he pulled his trousers right up to his knees. … In the models’ changing rooms, he found a red tulle petticoat and a gondolier’s hat. A tiny but wilful and crafty guy, who was almost disturbing, but he really made an impression on me, and I said to him: ‘You are the vilaine Lulu.’
