Her dazzling beaded blue gown was designed by Danish designer Jesper Hørving, which she has worn on several occasions since first debuting the one-shoulder dress in 2014 at the Bambi Awards in Berlin.
She then rewore it to the annual New Year's banquet at Amalienborg Palace on January 1st, 2016.
Speaking with 9Honey, the designer revealed that Princess Mary had fallen in love with the gown after seeing his fashion show.

The outfit was completed with her wedding tiara, diamond earrings from Bruun Rasmussen and a sapphire and diamond bracelet.
