Jewellery designer Wardrobe staple? Jeans, like everyone else I know. The favourites: Seven for All Mankind, Blue Cult, True Religion, Notify, Rock and Republic, and Acne. What do you look best in? Everything looked better on me when I was in my 20s. But if I had to pick something now, I'd say a slim top with fitted trousers or jeans and stilettos. I love my Gold Hawk mini-studded silk top. Top three fashion designers? Chloe, Diane von Furstenberg and Vera Wang. I also love Victoire de Castellane, the fine jewellery designer for Dior. She's a genius. Fashion no-nos? Grunge, Japanese school-girl spin-offs, large printed bottoms, bubble skirts, head-to-toe bright colours, lacy bras under white T-shirts and tacky jewellery. Handbag pick for this season? The Chloe Paddington, even though it's so heavy. I'm also loving YSL's oversized Muse in white. Favourite shoe designer? Christian Louboutin's platform wedges are adorable and comfortable. But my most comfortable pair of stilettos are silver sandals by Jean- Michel Cazabat. Must-have accessories? Dangly earrings and big cocktail rings or long necklaces and big cocktail rings. But never all of them together. Most expensive fashion item? A vintage Geoffrey Beene gown that I've worn once. Your fashion obsession? White ribbed tank tops. I wear them with everything: under jackets, sweaters, layered on top of each other or with thin, long-sleeved Ts. Who would design your Oscars dress? Oscar de la Renta. Every girl wants to feel like a princess. Your favourite shops around the world? Barneys, Henri Bendel, Intermix, Fragments and Calypso in New York; Maxfield's and Fred Segal on Melrose in LA; Le Bon Marche, Colette and boutiques around Saint Germain des Pres in Paris; any little shop in Florence. Fashion disaster? I bought a pair of 10cm ankle boots by Pierre Hardy. I wore them out of the store and found myself walking as if on stilts. They don't look so graceful today.
