All the Things Royal Family Members Never Get to Wear

All celebrities are scrutinized and always have been, but the members of the British royal family are watched, discussed, and judged with an intensity that's unmatched. (For example, it's believed that around two 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, it does so at a slow pace. Since clothing determines how we represent ourselves to the world, it's understandable that there's a lengthy set of wardrobe-related guidelines that the royal family must adhere to.

In the spirit of the royal family's newest member Markle (well, and Archie), we're highlighting some of the major wardrobe rules that she's going to have to get used to. Read on to see what they are via IRL examples on Kate Middleton, Princess Diana, Princess Eugenie, and Markle herself.

Can't Wear: Anything 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.

WHO: Princess Diana

Shop High-Neck Pieces

Can't Wear: Flat Sandals

Kate Middleton very rarely wears open-toed shoes at all, but when she does, they always have a heel. 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.)

On Meghan Markle: Goat Flavia Silk-Crepe Pencil Dress ($450, sold out); Tamara Mellon Siren Pumps ($450)

Shop Midi-Length Pieces and Stockings

Can't Wear: Large Handbags to Events

While Markle has opted for totes, crossbody bags, and sizable top-handle satchels in the past, she's been carrying clutches more and more as of late, as most royal family members almost exclusively do. (It's said to help them avoid awkward handshakes and cover up cleavage when exiting a vehicle.)

Shop Small Bags

Can't Wear: Fabrics That Wrinkle Easily

Say goodbye to delicate linen and silk if you join the royal family. In order to maintain a polished appearance, they opt for heavier fabrics that won't easily crease (e.g., tweed or wool). Fun fact: Princess Diana's wedding dress received criticism for being made of a wrinkly fabric.

On Princess Eugenie: Fiona Graham hat; Gainsbourg dress; M2Malletier bag; Valentino shoes

Shop Pieces Made With Sturdy Fabric

Can't Wear: Black to Daytime Events

Unless it's a funeral or another somber occasion, the royal family steers clear of black during the day and instead opts for colors that help them to easily be seen in a crowd.
