Going from playing a paralegal on TV to possible princess in real life means that Meghan Markle will trade her pencil skirts and career for evening gowns and tiaras.

The “Suits” actress and philanthropist, whose boyfriend Prince Harry is fifth in line to the British throne, shut down her lifestyle website The Tig over the weekend. That spurred speculation—reportedly denied by a source close to Markle—that this was done in deference to the British monarchy, which takes a dim view of hogging the pop culture spotlight while not on royal duty.

While royals have had careers of their own—Princess Margaret’s husband was a society photographer—and even carried out affairs with entertainment personalities, welcoming an actress into the House of Windsor would be unprecedented. For one, the profession has historically been held at arm’s length by the British establishment. “There’s a hundred years of suspicion and still remnants” of wariness, says Sarika Bose, a professor at the University of British Columbia who closely follows the royal family. “It would be groundbreaking if she were able to continue in her job.”

That’s even trickier if you’re a woman (even Grace Kelly had to abandon Hollywood to become Princess of Monaco) and expected to keep to “ladylike” engagements.  For instance, it was decided that while Kate Middleton would promote British fashion, the Duchess of Cambridge would stay away from glitzy fashion shows, longtime royal observer Sally Bedell Smith tells Moneyish.

That’s problematic for Markle, who has a clothing line of her own. “It’s an interesting distinction and the kind of adaptation she’ll have to make,” says Smith, author of a buzzy new Prince Charles biography.

However, there are two things in Markle’s favor if she ever becomes a Princess. For one, Harry is unlikely to ever be crowned King, thus giving his future spouse more leeway. “Harry is interested in taking up Diana’s mantle and pushing the monarchy in a direction it normally wouldn’t go,” says Arianne Chernock, a British history professor at Boston University. “He likes to have fun and be seen as of the people.”

The famously unhappy experiences of other female royals have also changed things. Princess Diana was seen as overly stifled and unprepared when she married Charles, and Crown Princess Masako of Japan became depressed partially because she had to abandon a job in the diplomatic service for palace life.

Nowadays, even the 90-year-old Queen encourages women to lean in: Kate Middleton “took a lot of stick at the time for not having a full time job and at one point the Queen was said to be concerned by Kate’s lack of direction,” says Katie Nicholl, author of a new biography of the Duchess of Cambridge.

That’s because Britain’s most famous working woman knows that lady professionals are good for the crown. “The monarchy has never been more popular and that has to do with their ability to capture the public imagination and admiration,” Smith said.
