Kate Middleton and Prince William stepped out tonight for the East Anglia's Children's Hospices Gala in Houghton Hall, Norfolk. For the event, which supports efforts to build a children's hospice, Kate wore a stunning blush Jenny Packham gown that looks very familiar.

She wore it in 2011 to the ARK gala, a dinner in aid of the childrens charity, Absolute Return for Kids. We're pretty much always interested in what The Duchess of Cambridge wears, but we were that June 2011 night in particular because it was the couple's first official royal engagement at Kensington Palace. They were married in April 2011.

Looks just as incredible now.
