King Felipe VI and Queen Letizia of Spain continued their weeklong visit to the US — their first one since taking the throne — with a stop in St. Augustine, FL, a former Spanish settlement. On Sept. 18, the royal couple looked airy and fresh, smiling and waving to fans while visiting the Castillo San Marcos during the 450th anniversary of the city. The King wore a sharp light gray Summer suit, with Letizia sporting one of her favorite floral skirts [1].
