The birthday girl – who is the eldest daughter of Crown Prince Haakon and Crown Princess Mette-Marit – took center stage in the photo, embodying royal glamor in a dark purple Alberta Ferretti dress borrowed from her mother . She also made her tiara debut, wearing the Boucheron Circlet Pearl Tiara, which was made for her great-great-grandmother, Princess Ingeborg of Sweden.
Princess Catharina-Amalia donned a candy pink cape dress by Natan Couture and Dutch star Tiara, a favorite of her mother Queen Maxima. Meanwhile, Princess Elisabeth opted for a strapless Armani Privé gown in pale pink, while her choice of tiara remains a mystery, not being known to be in her family’s collection, suggesting it it is either a gift or a loan. The youngest princess in the group, Princess Estelle, wore a sweet headband rather than a tiara. The little prince looked adorable in stylish shorts, knee high socks and a jacket.
The royal houses of Europe also posed for an official portrait, including Crown Princess of Denmark Mary and her husband Crown Prince Frederik, Queen Mathilde of Belgium, King of Spain Felipe VI, King of the Netherlands Willem Alexander and his wife Queen Maxima, Crown Princess of Sweden Victoria with her husband Prince Daniel, Grand Duke Guillaume of Luxembourg and Grand Duchess Stephanie. Also in attendance were newly engaged Princess Märtha Louise of Norway and Durek Verret, along with her three daughters, Emma, Leah and Maud Behn.
