This time, the Duchess of Cambridge was spotted at the red carpet premiere of "Mandela: Long Walk To Freedom" on Thursday night in London, wearing a white long sleeved Roland Mouret gown, with quite the daring leg slit.
But this isn't the first time we've seen Kate wear this dress -- back in May of 2012, the Duchess wore it to the Thirty Club dinner at Claridge's hotel in London.
This time, the new mom accessorized with a chunky silver statement necklace, a simple black clutch, and black pumps. She also wore her famous brown locks in a swept-back ponytail and kept her makeup quite simple, save for her signature black eyeliner.
The Duchess was accompanied by her handsome Prince William, who looked very dapper in a classic tux and bow tie. Also at the premiere were the film's stars, Idris Elba and Naomie Harris.
We think Kate looks stunning, and we love that she made an old dress look brand new again by changing up her hair and accessories.
What do you think of the Kate's ensemble?
