>> Last season, Julia Restoin-Roitfeld mugged for British chain Accessorize, and this season both she and her brother, Vladimir, are appearing in ads for Spanish chain Mango.  This isn't the first time they've worked together for a brand — Julia art directed the Fall 2008 Rock & Republic campaign that Vladimir appeared in — but as the mind recalls, this is the first time they've been faces for a brand together.  Carine's influence runs through both — Julia is styled like a portrait of her mother in these ads, with the kohl-rimmed eyes and brown hair flopping over one eyes; and Vladimir has taken his mother's favorite cause, amfAR, as his own — he's curating a photography exhibit during Fashion Week to benefit the foundation.
