It’s Fashion’s Night Out. And we are thrilled to hear that Mischa Barton has flown in from Los Angeles specially to introduce her super-cute handbag range at John Lewis. Osman Yousefzada and Tonia Bastyan will also be on hand to give customers style advice. While you’re there, grab a glass of champagne, watch a fashion show and indulge in some beauty treatments.
