FIRST AID: Personality disorders was the tongue-in-cheek theme of Olympia Le Tan’s new book-inspired bag collection featuring embroidered takes on the covers of novels including “One Flew Over the Cuckoo’s nest,” “Doctor Zhivago” and “Dr. Jekyll and Mr. Hyde.” The accessories designer feted the collection with a cocktail on Thursday night at the Museum of History and Medicine in Paris. Guests included Victoire de Castellane, Olivier Zahm and Gilles Dufour. Ben Gorham, the statuesque founder of Byredo perfumes, said he will be unveiling a new scent this month called Seven Veils. Ashley Smith, model and face of Diesel perfume “Loverdose,” said she was enjoying working with the Italian brand and looking at a possible design project. “ I love drawing so it would be cool to design something,” she mused.
