Queen Letizia of Spain, 46, looked stunning last night in a plunging navy blue number at a concert to commemorate the 40th anniversary of the Spanish Constitution.
The stylish Queen joined her husband of fourteen years King Felipe VI, 50, at the National Auditorium in Madrid for the event.
Her Majesty arrived for the concert in a navy blue satin dress with a pleated skirt and a dramatic V-neckline.
A panel of delicate blue lace with a nude lining underneath gave the outfit a very modern edge.
She teamed the glamorous look with a pair of coordinating suede pumps believed to be from Nina Ricci and a satin clutch bag.
The mother-of-two wore her dark hair in curls and tucked one side behind her ear to reveal a pair of beautiful diamond and sapphire earrings.
Letizia and Felipe, who are parents to Leonor, Princess of Asturias, 13, and Princess Sophia, 11, waved to the audience as they made their way to the auditorium.
The King of Spain wore a navy blue suit and red tie which coordinated with his wife’s outfit.
The royal couple joined the Spanish Prime Minister at commemorative concert.
