Prince Charles and Camilla, Duchess of Cornwall have a unique way of cutting cake! The royal couple cut a slice of cake with a sword on Monday to celebrate 70 years since Charles became the Duke of Cornwall. The pair was presented with the sword at a garden party at Boconnoc House in Cornwall. The duo looked stylish for their outing—Camilla rocked a teal blue sun dress with flowers while Prince Charles wore a gray suit with a lavender shirt and tie. They both accessorized their looks with sunglasses.
