Carine Roitfeld is to become Barneys guest editor and stylist for fall/winter 2011-12.

The former French Vogue editor - who left her position at the prestigious magazine in January - has teamed up with the US store to style and edit their Mario Sorrenti-shot advertising campaign, catalogue, newsletters, as well as the windows in their New York store, which will be unveiled in September.

Speaking about her new role, Carine told WWD: "It's very exciting. It's a new kind of project for me. It's good to have a new life, because now I can do projects that I never dreamed of before. For me, Barneys has always been the biggest name in luxury department stores, so to be able to participate in this project with them, and be visible during the next fashion week in New York, is my dream come true. To a French girl, it's a big, big dream."

Carine says she was drawn to the offer from Barneys because it gives her the opportunity to try something new.

She said: "To be on The Other Side with the retailers and buyers is new for me, and I always like new opportunities in my life. When I was doing my styling, most of the time I was thinking about a real woman who was going to wear the clothes. Sometimes I was thinking about myself, sometimes about a woman who really inspired me, but it was always about the woman. Working with Barneys, and choosing the looks, I was thinking about whether a real woman would buy this outfit and feel beautiful and comfortable."
