Andrea Riseborough sported a brand new ‘do when she took to the red carpet during the London Film Festival last night for the ‘W.E.’ premiere.

The formerly raven-haired actress showed off her newly dyed blonde tresses wearing a Christian Dior Spring 2011 Couture gown.

Her previous Dior Couture gown took our breath away, but I’m not having that same feeling on this occasion.

Whilst I prefer the runway version of this gown, Andrea’s military-style navy-and-nude tulle gown is more befitting to the fall season.

A whipsy updo, black satin peep-toes and an embellished clutch completed her look.

Which look do you prefer?

Runway or red carpet?
