She’s already fitting in with the royal family! Meghan Markle has a lot of rules to follow now that she’s married to Prince Harry, and one of them is that she can’t wear dark-color nail polish. Why, you ask? Simply because it doesn’t follow the royal etiquette Queen Elizabeth has instilled for decades. OK! magazine previously reported that royal sources have said wearing fake nails or colored nail polish is considered “vulgar” for royal engagements.

And at her royal wedding on Saturday, May 19, Meghan actually appeared to be wearing the Queen’s favorite shade — Essie’s Ballet Slippers. Her hairdresser reportedly previously described the color as “the only color Her Majesty would wear.”

It’s also been reported that Meg’s new sister-in-law, Kate Middleton, follows the same exact rule. For her wedding to Prince William in April 2011, the Duchess of Cambridge also opted for the Ballet Slippers color, just like Meghan! Kate, 36, has yet to be photographed wearing anything other than a neutral hue.

When Meghan and Harry stepped out for their engagement photos in November 2017, Meghan similarly donned a color that looked very much like Ballet Slippers. Since then, the Duchess of Sussex has been stepping out with lighter shades on her fingernails.

Perhaps that’s because she underwent intense princess training for months before the wedding. “She doesn’t want to ruffle any royal feathers. She wants to be ready for her new position and master all the ins and outs of what it takes to be a royal,” a source told Life & Style of Meghan prior to the nuptials.

We assume she learned all those royal family beauty tips during that training as well. “The classes will also include dining etiquette and privacy rules,” the insider said of Meghan’s previous three-week-long sessions. “There will be lessons on how to handle difficult family members with dignity and class, and crisis management, as well.” Keep on following the rules, Meg!
