Today, Queen Margrethe hosted a lunch on the Royal Ship Dannebrog to mark its 90th anniversary.

Crown Prince Frederik, Crown Princess Mary, and Princess Benedikte also attended the celebration.

The Dannebrog has been used as an official and private residence by the Royal Family during summer cruises in Denmark or on official visits abroad since 1932.

Queen Margrethe wore a red and white outfit with her Revillon bag.

Crown Princess Mary wore her Ole Yde dress with her Gianvito Rossi pumps as well as Dulong and Cartier bracelets.
