Charlotte Gainsbourg is friggen awesome. Her natural elegance, individual beauty and soft coo of a voice are mesmerising in films like The Science of Sleep and Prête-moi ta main. She does what Gallic girls do so well: understated charm. What is it about being French that gives women the ability to make jeans look like couture? With her effortless chic, she is muse to Balenciaga’s Nicolas Ghesquière, the face of French label Gerard Darel and has guest edited Vogue Paris. Of course it doesn’t hurt to have the gorgeous Jane Birkin and charismatic Serge Gainsbourg as parents – but famous lineage aside, the tailored red-carpet glam and insouciant street style that has made her a fashion icon is pure Charlotte.
