State dinners when heads of government and members of royal families meet one another are some of the grandest and most glamorous events. Not only do such affairs celebrate diplomatic ties, but we also get a great opportunity to enjoy their choice of outfits.

One of the most recent state dinners took place in Denmark where the Danish royal family welcomed French president Emmanuel Macron and his wife Brigitte. Of course, Crown Princess Mary, Princess Marie, and Queen Margrethe made heads turn with their spectacular tiaras and gowns.

Princess Mary opted for a white formal dress with black watercolor print on it and a full skirt. She teamed the gown with one of the Danish royals’ most beautiful jewels – the Ruby Parure Tiara.

Meanwhile, Princess Marie sported an off-the-shoulder crimson dress with a traditional headpiece. The last but not least, the monarch stepped out in a black lace dress with pearls and looked regal in her Pearl Poire Tiara.

Royal watchers absolutely love when Princess Mary wears her favorite headpiece
