Keira Knightley relived her wedding day on Tuesday night (03Dec13) by taking to the red carpet in the designer gown she wore for her low-key nuptials.

The Pirates of the Caribbean beauty married The Klaxons star James Righton in the South of France in May (13) in front of just a handful of friends and family.

She wore a simple Rodarte dress with a tulle skirt for her big day, one that fans had already seen her in at a British Academy of Film and Television Arts (BAFTA) event in 2008.

Knightley gave the dress another outing by wearing it at the Serious Fun charity gala in London, changing the look of the frock only slightly by adding a sheer, beaded overlay.

The event was held at the Roundhouse venue in the U.K. capital and raised funds for global programs to help children with serious illnesses.
