Julia Restoin Roitfeld, New York-based Parisian art director, style maven, mother and sustainability champion, has been chosen as an ambassador for H&M’s Conscious Exclusive Collection. Known for her personal sense of style, Julia is the embodiment of modern cool. She is a citizen of the world, aware that every move we make — from the way we consume to the way we treat waste — will have a broader, global impact on our environment.How do you feel about being named ambassador of the new Conscious Exclusive Collection for H&M?I feel flattered and proud. It's a great idea to use fashion as a way to create awareness around sustainability. We all have to be more careful about the way we inhabit this world, and fashion can be part of the plan. Sustainable fashion is creative, inventive and responsible - everybody can enjoy it while doing something good for the planet.How important is sustainability in your life?It's not simply a matter of how we deal with trash and recycling; sustainability is a lifestyle that encompasses the way we consume, the way we behave and the way we dress.Can sustainability be fashionable?Definitely. Sustainability is a creative way to make fashion and to use fashion. Making new clothes from old; recycling glass into embroidery; mixing and matching old with new, and being responsible about what we buy and consume.Your family is involved in the fashion world. Is style something you are born with or something you acquire?A little bit of both. A part of it is innate, but it is also something you acquire as you grow up. Style is just like everything else in life - you learn from other people, as well as from yourself and the mistakes you make. It's a never-ending process.How would you define your style?Defining one's own style is not easy. I'm very instinctive and I'd say that my own style is minimal and classic. I never go for something over the top; I wear what I like and feel comfortable in.How would you describe the Conscious Exclusive Collection?It's a mix of historic feelings and modern shapes condensed into a wardrobe of separates that every woman can wear in her own way. Old paintings and classical motifs are splashed onto clean-cut pieces, to striking effect. It makes for clothes that are fun to wear, and unique - always a plus in fashion...
