Many girls dream of becoming a princess when they grow up, but little do they know that the fancy title comes with a lot of responsibilities and strict rules.
While there's a lot of wealth and privilege that comes with being a royal, everything they do, down to the tiniest detail, is predetermined by laws and tradition that date back centuries.
For instance, the Queen and her family aren't allowed to have any political views or run for office and they're barred from publicly speaking about politics.
These rules not only apply to those who are royal by blood, but also extend to those like Kate Middleton and Meghan Markle, who became a part of the British monarchy by marriage.
Kate and Meghan, who are married to Prince William and Prince Harry respectively, are expected to dress and behave a certain way, and although they do break protocol often, they never push the envelopes too far.
For Kate however, there is a time in her life that she likes to be a rule breaker, and it's during her pregnancies, especially when it comes to fashion.
The Duchess of Cambridge is usually dressed conservatively when carrying out her official studies, sticking to longer hemlines and sleeves, but when she's expecting, she likes to be a bit more daring.
While many pregnant women opt for longer frocks, like maxi dresses, Kate went for shorter styles.
As Cecile Reinaud, the founder of one of Kate's favorite brands Seraphine explained, this is a trick the mother of three did while pregnant because "highlighting legs and arms is always a good trick to keep a nice silhouette."
"She went shorter, on a couple of occasions well above her knee, which she never does normally," Reinaud told InStyle. "And especially in winter, because when she wore opaque black tights, it looks okay. It doesn’t look too much because it’s not bare legs, it’s black opaque tights with a shorter dress."
The designer predicts Meghan, who recently announced she's expecting her first child next spring, will be taking a page out of Kate's maternity style book.
"Because her pregnancy is going to be a winter pregnancy, I think she’s more likely to shorten her hemline," Reinaud added. "And also [she'll] probably wear what we’ve seen at [Eugenie's] royal wedding, this kind of coat dress."
The Duchess of Sussex was still in the early stages of pregnancy when she embarked on a 16-day royal tour through Australia, Fiji, Tonga and New Zealand, so she kept her maternity style chic by mostly wearing below-the-knee dresses and tailored separates.
But as her bump grows, we should expect to see her switch up her style and opt for shorter looks, which she's already proven she can pull off perfectly.
Meghan has not attended any engagements since her trip Down Under came to an end, but royal watchers are eagerly waiting her for return to the spotlight this weekend.
Along with the other members of the royal family, the duchess is will be taking part in three Remembrance Day events, including the annual service at the Cenotaph.
