And we love her Spring Summer 2013 choice from fashion designer, Victoria Beckham, with peter pan collar, pencil skirt and mesh panelling. Rosamund also injected some extra personality into the look by adding a pop of colour, with a peek of neon pink beneath the dress's lace inserts, paired with pink and nude heels.

Accessorised simply, with Tiffany & Co. rings and her blonde short hair side-parted in a neat bob, we think Rosamund Pike stole the show with this refreshing look.
With The World's End opening in cinemas 19 July, we can't wait to see Ms Pike take a turn in the tongue-in-cheek action film.
