There are a lot of rules surrounding what the royal family can and cannot do. Interestingly, there doesn't seem to be a particular entry in the rulebook about tattoos. But as the guidelines include that "Nude stockings must be worn to public engagements" and "You cannot take off your coat in public," we're guessing they're not super-fans of body ink. In fact, Princess Eugenie is the only modern higher-ranking royal known to have a tattoo. (Or, at least, a visible one — who knows what's lurking beneath all those button-ups and coat dresses!)

As for less-major royals, we've caught a glimpse of a few other tattoos. For example, Lady Amelia Windsor, third cousin of Prince William and Harry, has at least a handful of tattoos. The British model and sustainable fashion influencer has a tiger on the back of her shoulder, as well as a few designs on her side and wrist. Outside of British royalty, Princess Sofia of Sweden, Princess Stephanie of Monaco, and even Prince Frederik of Denmark all have some form of ink.

Today, we think of "The Firm" as frowning upon tattoos, but historically, they're actually not uncommon within the family. Prince Alfred, Duke of Edinburgh, received one in 1869, while Princes Albert Victor and George of Wales (who became King George V) got theirs as teenagers. The teens' ink was sanctioned by their father, King Edward VII, who had ink of his own in the form of a Jerusalem Cross on his arm.
