For Queen Mary of Denmark, she found the perfect combination of elegant and cozy when she attended a state banquet with King Frederik on Wednesday, January 28. Queen Mary debuted a long-sleeved burgundy gown by Elie Saab for the occasion, with the belted dress including a dramatic cape that sweeps across the front of the design. She paired the gown with her royal orders and one of her most cherished tiaras, known as the Edwardian Tiara or Diamond Necklace Tiara.
