The Duchess of Cambridge is in a Spring state of mind! On Monday, Kate Middleton made a glamorous appearance [1] at the 105th anniversary celebration of the Goring Hotel in London, where she stayed the night before [2] her wedding to Prince William in 2011. Nearly four years after that memorable day [3], Kate had her baby bump front and center in Erdem's flattering Darla dress. Kate's been solo in recent days as Prince William continues his royal visits [4] to Japan and China, but the two shared plenty of time together during their recent trip to the Caribbean [5] with Prince George.
