Unless you're eagle-eyeing the royal family's hands, you might not notice that the women are never spotted with colored nail polish. According to OK! magazine, the royal family—particularly women like Kate Middleton, Queen Elizabeth, and now, Meghan Markle—are prohibited from wearing non-natural-looking nail polish, which is why they often stick to nude and taupe colors. In fact, according to Refinery29, the royal women swear by Essie's $9 nude nail polish. Middleton's favorite shade is Allure, while The Queen is known to sport Ballet Slippers. Only time will tell what Markle's go-to shade will be.
