Sienna Miller attended the 2011 Annual International Medical Corps Awards yesterday in Beverly Hills, California where she was honoured.

The British actress looked very pretty wearing a Twenty8Twelve Fall 2011 romper.

Her simple black ‘Neuve’ romper with sheer sleeves was paired with black tights and Jimmy Choo ‘Fei’ open toe ankle boots which are barely visible on the red carpet.

Gold hoop earrings and gold rings accessorized the look, but I’m more obsessed with her top knot.

We all know that Sienna is not one to do pay much attention to her hair, so this effort is a welcome change.
