VIDEO : Kate Middleton Sports A Floral Frock For Mental Health Charity Meeting

Spring is in the air for Kate Middleton?or at least on her clothes. On Tuesday, the Duchess of Cambridge stepped out in a colorful floral frock alongside her husband, Prince William, and brother-in-law, Prince Harry, in honor of their Heads Together mental health campaign, which they spearheaded together a year ago. The royal mother of two paired her elegant daytime ensemble by Erdem with a burgundy clutch and coordinating Tod's leather pumps. The trio arrived in London to discuss their organization ahead of the 2017 Virgin Money London Marathon.
