Moving from her usual residence in New York to London - "My boyfriend [Robert Konjic] is in London, so I'm spending the summer here, I've been here for a couple of months now," she tells Grazia - Julia Restoin-Roitfeld isn't in the capital purely for leisure. Style.com reports that the design management graduate is the face of the forthcoming Lancome collection for Spring, Ultra Lavande, and was recently shot by Mario Testino for the campaign.

Alongside modelling for the beauty brand, Restoin-Roitfeld has taken on the role of creative consultant for Mark Fast's lower-priced line, Faster, and was on set to offer her advice for the line's Fall lookbook on Tuesday. "It started after I saw two friends wearing [Mark's] dresses [one of which was model Anouck Lepere]. I was asking 'Who designed those dresses! I want one!'" she explains of how she came about the position. "I especially wanted to wear one for the Cannes film festival, and that was my first dress by Mark."

"So that's how we met. Amanda [Mark's Art Director] heard that I was working doing creative consulting. So they asked, and I was very happy to work with him and bring my ideas to the brand. Mainly it's about being able to bring an outside point of view because they [Mark's team] all work together already. [I] mostly [work] on branding, and the image of the brand."
