Duchess Kate and Meghan Markle coordinate their blue looks for first joint royal engagement

By Sophie Hamilton

The Duchess of Cambridge and Meghan Markle had a case of the blues on Wednesday (Feb. 28), but that was only where their coordinated ensembles were concerned. Looking sensational as they joined Prince William and Prince Harry at their first offical royal appearance as a foursome, the royals were dressed to impress at the first annual Royal Foundation Forum in central London. Turning to one of her favourite maternity brands, pregnant Kate looked radiant in a cornflower blue Seraphine dress with button details, which she paired with pumps. Meghan turned to a navy trench-style dress by Canada-raised, New York-based Jason Wu, looking fabulous as she anchored the look with black pumps featuring an ankle strap.

The event was themed 'Making a Difference Together,' showcasing the programmes run by The Royal Foundation, which includes causes close to the young royals' hearts: Heads Together and the Invictus Games. The two royal couples were all smiles as they appeared on stage together to discuss the Foundation's projects. After the royal wedding in May, Meghan is due to become the fourth Patron of The Royal Foundation.
