Must-have Brands: Costume National, Dolce & Gabbana
Style Icon: Anna Wintour, Miuccia Prada
Philosophy: I like a mixture of classics and funky highlights. For me fashion is all about creativity: the perfect execution of a line, craftsmanship, fabrics, an utterly original print. I love the different ways a piece can feel depending on how you style around it: the perfect outfit for me is one that can move effortlessly from workday to night out with just a change of bag or some new accessories.

Must-have Brands: Marc Jacobs, Vivienne Westwood
Style Icon: Mary Kate Olsen, Sienna Miller
Philosophy: I like to dress for nights out ... feminine, funky, young, flirtatious. Perfect dresses and of course heels, color on black, lots of jewelry, mixing vintage and contemporary ... fashion is like a signature. You start with the basics and build a set of punctuation points that are all you.

Must-have Brands: Alexander McQueen, DSquared2
Style Icons: Joan Jett, Debbie Harry
Philosophy: I'm definitely the most rock and roll of the group. I love denim and leather, motorcycle chic, boots, thick heels ... I want to feel like wherever I end up I'm going to look great and feel comfortable. Rock and roll just never goes out of style, and there's almost nowhere where it doesn't work. It's all in the attitude.

Must-have Brands: Michael Kors, Burberry
Style Icon: Princess Diana, Grace Kelly
Philosophy: I love clothes that exude elegance and classic femininity. Whether it's evening gowns and heels or jeans and boots, I look for timeless items, movie star glamour, a touch of refined fantasy ... One doesn't have to do too much, start with good taste, add elegance, and that's true beauty. And always remember, it's the woman that makes the dress, not the other way around.
