Black Only For Certain Occasions
As we mentioned, there are a lot of rules about how Kate must dress. One big no no is wearing black during the daytime. Kate, her family, and now Prince George can only wear black when they are in mourning.
Black Always On Hand
Besides that, all members of the Royal Family must pack a set of black clothes when they travel outside of the country. Why? If anyone dies, they can easily come back and attend the wedding in proper attire. The rule first came about when George VI died, and the Queen was on a trip to Africa. She didn’t bring black clothes to change into, so she was late.
