Despite the rain, the Duchess of Cambridge looked sunny donning a label she has never worn before: Altuzarra. The mom-of-two showed off her trim figure wearing the label's blue polka-dot "Aimee" button-front dress, which features a V-neckline and slit. Kate accessorized the school look with a pair of tan heels and a matching clutch bag. Photo: Chris Jackson/Getty Images

The engagement, though, got off to a shaky start as William rushed to the aid of Lord Lieutenant of Essex, Jonathan Douglas-Hughes, who tripped and fell. Photo: Chris Jackson/Getty Images

Inside, the Duke and Duchess listened to moving stories from those assisted by Heads Together and Place2Be. “My daughter is really confident on the outside but actually when it comes to exams she just buckles,” one parent shared during a discussion with the royals.

At one point, Prince William joked: "Sometimes I still feel like I am 16, to be honest sometimes I still act like I am 16." His wife Kate agreed, quipping: "I still think you're 16."Photo: Twitter/‏@KensingtonRoyal

The Prince also gave students an offer they couldn't refuse! "We should swap places - I can come back to school and you can do my job," he joked.Photo: Twitter/‏@KensingtonRoyal

The visit is just the latest in what is shaping up to be an exciting month for William and Kate. In about a week they will be headed to Canada with their two children George and Charlotte for a royal tour.Photo: Twitter/‏@KensingtonRoyal
