Whenever they travel, royals are forced to carry black attire in their luggage. The reason behind it is quite sad. They have to be prepared in case someone in the family passes away. This is because back in 1952, Elizabeth II was in Kenya when she heard her father had died, and after coming back to London, she had to wait for a mourning outfit to be delivered to her before she could exit the plane. It wouldn’t have been right to do so without the appropriate attire.
