The 81-year-old looked to be in a great mood! Margrethe wore a red jacket, paired with a maroon skirt — and her hat even matched.
She posed outside Koldinghus, the 750-year-old castle, which has been turned into a modern museum.
"Kolding's old royal castle, Koldinghus, today formed the framework for three festive events, when Her Majesty the Queen and Her Royal Highness Princess Benedict participated in the official opening of the Royal Collection Koldinghus and in two exhibition openings," an Instagram post read about the sisters' outing.
"'This is a day that many of us have been looking forward to,' the Queen said in her speech before Her Majesty officially opened the exhibitions. At the same time, the Queen thanked her sister Princess Benedict for agreeing to be the honorary patron of the Royal Collection Koldinghus," the message continued.
"In the exhibition 'The Queen's Embroidery,' Her Majesty presents for the first time a selection of around 100 private embroideries. The embroideries have the Majesty either herself in use or given away as a gift. The colors and motifs are adapted to the person who is to receive the gift or the room where the embroidery is to adorn. The exhibition 'Christian 5. - King, warrior and the anointed of God' shows royal treasures, which are connected to the story of Christian 5., and many of them are shown outside the capital for the first time. 📸 Kongernes Samling / Maria Tuxen Hedegaard © ️," the message concluded.
For her part, Princess Benedikte wore a patterned dress, which she paired with a purse and blue pumps.
The princess is known for being well-dressed, and she previously discussed her passion for fashion.
“I make an effort, I will admit. I went to Margretheskolen for a year, where we learned to sew, make patterns and design. Therefore, I know what it is about. Even though handicrafts still is a great interest of me, it has not become so much about self-production after I went to school," she said.
"At the turn of the year, Kongernes Samling took over the operation of Koldinghus, which is now in the company of Rosenborg Castle and the Amalienborg Museum. In [the] future, Koldinghus will help to disseminate the Kings' Collection, which contains central objects and works of art that tell about Danish royal history and about Denmark's kings and queens. Today the official opening takes place and Her Majesty the Queen and Her Royal Highness Princess Benedict both attend the festivities," another message read on Instagram.
The statement continued, "Her Majesty and Her Royal Highness were received on arrival at Koldingshus by the museum director of the Royal Collection, Thomas Thulstrup, and in the castle courtyard the Queen and Princess were welcomed by the Gardehus Regiment's signal march. His Excellency Count Ingolf and Countess Sussie of Rosenborg are also present at today's festivities."
