All celebrities are scrutinised (and always have been), but the members of the royal family are watched, discussed and judged with an intensity that's unmatched. It's believed that around 2 billion people around the world watched Prince Harry and Meghan Markle's wedding. The royal family is an institution that's steeped in tradition and formality, and while it does evolve and modernise, it does so at a gradual pace. Since clothing determines how we represent ourselves to the world, it's understandable that there's a lengthy set of wardrobe-related protocols that the royal family must adhere to on royal tours and official visits.
In the spirit of the royal family's newest member (Meghan Markle, in case you forgot), we're highlighting some of the major wardrobe rules that she's going to have to get used to.
Can't Wear: Anything Too Low-Cut
While a turtleneck isn't required, modesty is the best policy in the royal family, so you won't find many (if any) cleavage-baring tops in their closets.
Can't Wear: Flat Sandals
Kate Middleton very rarely wears open-toed shoes at all, but when she does, they almost always have a heel. Hence the countless pictures of her playing sport in wedge espadrilles. When she wants to wear flats for a less-than-formal occasion, she sticks to ballet flats, boots or white sneakers. That said, her most-worn shoe style is classic pumps.

Can't Wear: Bare Legs/Short Hemlines
While this tradition is said to be loosening up, royal family members usually wear stockings with dresses and skirts for formal occasions, and short hemlines are a no-go. (We fully expect Markle to ignore this "rule" on occasion, as she did for her and Harry's engagement photos.)

Can't Wear: Black to Daytime Events
Unless it's a funeral or another sombre occasion, the royal family steers clear of black during the day and instead opts for colours that help them to easily be seen in a crowd.
