The Depressing Reason the Duchess of Cambridge Always Packs This Outfit When She Travels

There's only one outfit we know the Duchess of Cambridge always packs, and that's something black. This is on purpose, because according to The Independent, the royal family is required to pack a black outfit for mourning. The strict rule's in place in case anyone in the family dies while they're away. That way, he or she can change into the spare attire upon arrival in England. As morbid as all this sounds (who wants to think about this while travelling?), you have to admire the royals for being so prepared, especially since Prince William and Kate are often abroad.
