The Duchess of Cambridge dazzles in Altuzarra dress on back-to-school royal visit

The Duchess of Cambridge debuted a new dress on Friday (Sept. 16) as she stepped out to visit a school for the Heads Together campaign in Harlow, Essex. For the first time ever, the mother of two wore a stunning creation by French designer Joseph Altuzarra.

The 34-year-old accessorized the pretty sky blue dress with black and white polka dots, which retails for approximately $2,285, with a pair of pale pink heels and a matching clutch bag. Her long brunette hair was styled in her signature bouncy blow dry, and the Duchess kept her jewellery simple with a silver necklace, drop diamond earrings and her beautiful engagement ring.

Prince William and Kate visited Stewards Academy to learn more about the pressures facing young people as part of their Heads Together campaign, which aims to aid mental health in young people. On her way into the school, Kate accepted a bunch of yellow roses and she and the Prince spoke to two students, asking them about their badges.

The couple then waved at the cheering crowd before going inside where they joined in on a class, laughing as the students greeted them in unison, saying: "good morning Your Royal Highnesses, and guests," before taking their seats.

The second-in-line to the throne recently wrote a blog post for the Heads Together campaign ahead of their trip to the school, revealing his hopes that Prince George and Princess Charlotte feel supported academically and emotionally at school, writing: "The truth is, for many young people, changing schools or starting a new academic year is really difficult to deal with.

"Catherine and I have young children who will be going through this themselves in a short period of time, and like all parents we will want to make sure that our children are not just able to achieve their academic potential at school but are also happy and emotionally supported."
