The Royals, Prince William, Kate Middleton and Prince Harry marked the World Mental Health Day, and headed to The London Eye to represent their campaign Heads Together.

The three took a ride on the London Eye with young people who have battled psychological problems, and have been brave enough to share their experiences.

The Duchess of Cambridge, Kate Middleton, who has recently been wearing more high-end designs, looked mesmerizing in a floral printed pleated dress from Kate Spade New York.

Kate's purple rose printed dress retails at £428, and was first seen on her during her Royal Tour of Canada a few days back.

The summery knee-length dress was styled with Kate's trusty suede nude heels and a nude clutch, and the Duchess topped it off with dangling diamond earrings and her brunette hair styled into soft curls framing her face.
