"I did not have any understanding of just what it would be like", she said, saying there was a misconception that because she was an actress she would be used to being in the media spotlight.
As she got to know Harry, Markle learnt about the huge amount of public scrutiny that the royals face, and she said she was not prepared for the level of attention their relationship would have. He also sought the blessing of Meghan's parents, Thomas Markle and Doria Radlan. The pair dated for almost a year and their wedding will occur sometime in the spring of 2018, royal officials announced.
As for Markle's footwear, she opted for Aquazzura's nude "Matilde" heels-which are now on sale for $465 (shop them up while you still can here).
He designed the ring himself - it contains one diamond from Botswana, a country he visited numerous times, and two from his late mother princess Diana's personal collection.
Ms Markle spoke about her love for the prince for the first time in September - telling Vanity Fair magazine: "We're two people who are really happy and in love".
"He knows commentators will say this is "the price she has to pay" and that 'this is all part of the game.' He strongly disagrees".
The prince said Ms Markle would easily take to the role of being a member of the Royal Family and said they were a "fantastic team".
William and Kate said they were "very excited for Harry and Meghan", adding "it has been wonderful getting to know Meghan".
"The ring is obviously yellow gold because that's (Markle's) favorite and the main stone itself is sourced from Botswana and the little diamonds either side are from my mother's jewelry collection to make sure that she's with us on this insane journey together", Prince Harry said in an interview with BBC on Monday. "But we're happy. Personally, I love a great love story", she continued, referencing their choice to keep private.
"The Queen and The Duke of Edinburgh are delighted for the couple and wish them every happiness", said a message on the monarch's official Twitter page.
Until recently, a union with Ms Markle would have ruled Prince Harry out of succeeding to the throne - due to her being a Roman Catholic.
It is rumored that upon her move to Kensington Palace, Markle would give up acting and focus all of her energy on philanthropy.
'But with teh ring and everything else going on, I'm sure she's with us, jumping up and down somewhere else'.
