Sienna Miller ruled the ‘Best Dressed’ list at Cannes Film Festival last week but it’s not just the red carpet where her style shines, with her casual daytime efforts just as deserving of fashion credit.

In between red carpet appearances in Cannes she wore this cool, feminine outfit, pairing a striped shirt with a diagonally striped skirt and uber on-trend suede mules. Stripes are the pattern of the summer and Miller’s modern take on the Riviera classic has us all waiting in line to steal her look. If you can’t get enough of this season’s stripes and are dying to get your hands on those must-have mules, take a look at how you can emulate her ensemble…
