October 3 marked a big day in the royal world as Grand Duke Henri of Luxembourg abdicated the throne in favor of his eldest son, the now-Grand Duke Guillame. Celebrations were held at the Grand Ducal Palace to honor Guillame and his wife, Grand Duchess Stéphanie, taking the throne, and two future European queens were among the glittering guests. Swapping elegant daywear for tiaras and gowns, both Princess Catharina-Amalia of the Netherlands and Princess Elisabeth of Belgium wore dresses that were reminiscent of Princess Kate's best evening gowns.
Princess Elisabeth, who is currently studying at Harvard, flew to Luxembourg to join her parents, King Philippe and Queen Mathilde, at the historic event. Wearing a sculptural navy dress by her mother's favorite designer, Natan, Elisabeth looked every inch the future queen during the daytime ceremony—but she went into full sparkle mode for the evening gala.
