Markle also has a history of getting political.
The blueprint for the wedding is said to be Prince Edward's marriage to Sophie Rhys-Jones (now the Countess of Wessex) Their wedding in 1999 was dubbed "the people's wedding" after wedding organizers ran a ballot for hundreds of people to be invited into the grounds of the castle. She's signed an autograph, wore her hair in a messy bun, and-dare we say it-stepped out without pantyhose.
In addition to her refreshingly modern dress sense and public displays of affection with her fiancé, Meghan broke one of the biggest rules in the royal family rulebook - don't get involved in politics. It's not every day that a royal gets engaged to an American actress, after all.
When Prince Harry and Meghan Markle first revealed the details of their wedding, they stated that they wanted to "allow the public to feel part of the celebrations". "I fundamentally disagree with that because women don't need to find their voices".
She even went so far as to speak out about the #MeToo and Time's Up initiatives specifically.
The Huffington Post claims that these types of statements are very odd coming from royals, who generally stay away from political stances or biases.
The 1,900 guests at Westminster Abbey included around 1,000 friends and family members along with foreign diplomats and leaders, religious leaders and 80 people who worked for charities supported by the Prince.
It's not common for royals to show affection in public, or much less hug a stranger.
"Kate's calmer, simpler approach, sitting back in her chair with a rather demure hand clasp gave a glimpse of what being a royal must have taught her, which is that people listen anyway with no need to ramp up the passion and drama".
She also suggested she would have to wait until after her wedding on 19th May before committing to the upcoming projects: "I guess we wait a couple of months and then we can hit the ground running", she laughed. "We're stuck together for the rest of our lives!", said prince Harry during the event with a sense of humor.
And now it seems the LA-native has picked up one particular move that will stand her in good stead.
While the future sisters-in-law colour coordinated in blue, Prince William and Harry were spotted twinning in black suits and white shirts.
Harry told the crowd of Markle, "I am personally incredibly proud and excited that my soon-to-be wife, who is equally passionate about seeing positive change in the world, will soon be joining us with this work".
