Sienna Miller's Effortless Party Style? It's All About Print

We'd love to have Sienna Miller as one of our most loyal supporters - she's never going to let you down when it comes to dressing the part.

The 31-year-old actress and mum of one turned out to support stepmother and Dragons' Den star Kelly Hoppen at the launch party for her new book, Design Masterclass, on Monday - and it goes without saying Sienna was the undisputed belle of the ball.

The actress looked her usual effortlessly cool self in a high-necked camel Burberry dress complete with eye-catching print.

She teamed the dress of our dreams with chunky heels, opaques and a clashing furry cropped jacket, as she sipped Perrier-Jouet champagne and rubbed shoulders with the likes of Victoria Beckham and Jo Wood.

A nonchalant hair and beauty look - classic high meets low maintenance Sienna style - was the icing on the cake.

Monday nights have never looked better.
