Tiaras Parade at the Royal banquet in Norway. Queen Mary wears The Pearl Poire for the first time

It marked a very special night for King Frederik and Queen Mary as they stepped out for a gala dinner in Norway on the same day as their 20th wedding anniversary. Dressed in white-tie attire for the dinner, King Frederik donned his military uniform, while his wife Queen Mary wowed in a lavender gown by Birgit Hallstein, first worn in 2015, and made her debut in the Pearl Poire tiara.
