As you already know, tomorrow is the coronation of King Charles III. While we love to see the Prince and Princess of Wales, it’s particularly exciting to see nearly every queen, king, prince, and princess in the world gathered at one event. Tonight, Buckingham Palace hosted royalty from around the world for a coronation reception, and the outfits were so regal. 

Royals from Spain, Denmark, Japan, Thailand, Morocco, Sweden, and other countries descended upon the palace in their chicest looks. The dress code clearly called for relatively casual cocktail attire, as there wasn’t a single tiara or crown in sight. Scroll down to see all the best looks from the coronation reception in London.
