Lou Doillon showed her support at the Burberry Paris Boutique Opening yesterday evening.

The French actress and model wore a classic trench with orange detailing from Burberry Prorsum Resort 2012.

Melanie Laurent: take note; this is how you wear a trench as a dress.

With just a simple black shirt, tights and pumps, Lou transforms a simple, albeit beautiful, coat into total French elegance.

Wavy, messy hair and minimal makeup complete the look.
