Pictured: Ambassador Dung arrives at the Royal Palace in horse drawn carriage called a gala coupé, a tradition dating back to the late 19th century.

At official ceremonies in Sweden the horses are dressed up in State-harnesses when put to the Royal carriages. 

The Gala Coupé is used for all ambassadors when they arrive at the Royal Palace to hand over their credentials to the King.

Further, the Crown Equerry, Equerry, Coachmen, Outriders and Footmen are dressed in elegant liveries and uniforms that contribute to the beauty and elegance of the Royal equipages.
