Meghan, 37, is known for regularly stepping out for royal engagements in her power suits.
Although she has quickly adapted to many of the minutiae of royal dos and don’ts, she “has found certain rules in the royal household difficult to understand, like the fact that the Queen prefers women in dresses or skirts rather than trouser suits, and is often asking Harry why things have to be done in a certain way,” a source previously told PEOPLE.
“I think she finds it a little frustrating at times, but this is her new life, and she has to deal with it,” the source added.
Meanwhile, the Duchess of Sussex visited King's College London on Wednesday to address important issues including human trafficking and modern slavery, gender equality and inclusion, peace and reconciliation, and climate change and resilience.
