The Future Queen of Norway Trades Camo Fatigues For a 125-Year-Old Tiara and Her Mom's Old Evening Gown

Princess Ingrid Alexandra celebrated her 21st birthday earlier this year, and now she's marked two other huge milestones. The princess, who is set to become Norway's future queen one day, officially completed her compulsory military training earlier this month, and on April 8, she took part in her first state visit. For the occasion, the military graduate swapped her uniform for a sparkling tiara—and while her jewels were more than a century old, her gown was also a familiar piece.

The princess joined her parents Crown Princess Mette-Marit and Crown Prince Haakon for a state banquet held in honor of Iceland's president Halla Tómasdottir and her husband Björn Skúlason. Ingrid Alexandra looked stunning in a pale blue evening dress featuring asymmetrical tiered ruffles, pairing the gown with the Boucheron Pearl Circle tiara.

If the dress looks familiar, it's because Ingrid Alexandra's mother wore the same pale blue gown to Crown Princess Victoria and Prince Daniel of Sweden's 2010 wedding. In a sweet full circle moment, Princess Ingrid Alexandra—who was a flower girl in Victoria and Daniel's royal wedding—posed with her mother for photos when Mette-Marit wore the tiered dress.

Princess Ingrid Alexandra received her glittering tiara as an 18th birthday present in 2022, and according to The Court Jeweller, it "was likely purchased by Prince Carl of Sweden from Boucheron" after the luxury jeweler showed the piece at the 1900 Exposition Universelle in Paris. The tiara was then passed down through the Swedish and Norwegian royal families, and most recently was owned by King Harald of Norway's sister, Princess Ragnhild, who lived in Brazil until her 2012 death.

While it's unknown how the design—which features overlapping diamond circles with pearl accents—came into Ingrid Alexandra's possession, it once belonged to her great-great-grandmother Princess Ingeborg. Princess Ingrid Alexandra wore the historic tiara for her official 18th birthday portraits as well as to her lavish birthday party, which was attended by three other future European queens.

As for her military service, Private Alexandra told reporters (via Royal Central), “It will be very nice [to graduate] in one way, but also very sad, because there are many people I have gotten to know well and have grown to love very much."
