Camilla, Duchess of Cornwall regal in red with Donald Trump ahead of NATO Leaders Summit

Melania Trump also stood out with her choice of bold colours for her meeting with the royals.

Donald’s wife wore a striking yellow Valentino cape coat, retailing at £4,600, to keep warm from the cold London air.

The cape coat was a joyful canary-yellow and is described by Valentino as a “soft wool blend with a trace of cashmere to a sweeping silhouette.”

The coat has been crafted into a long and graceful shape with extra material draping around the neck and over the shoulder, proving some extra warmth and protection from the chilly winter evening.
