"The Queen is the most well-travelled monarch in history and it's been fascinating to see how she has passed on her experience to the younger generations of the royal family". Meghan reveals that a tiny fragment of blue material was sewn on to her outfit.
Givenchy's Clare Waight Keller designed a modest white bridal gown for the royal wedding.
Meghan also included the poppy, the state flower of her home state of California, in a nod to her American roots in the veil on her wedding day. "The thinking behind for me, [was to include] some sort of representation of all 53 of the Commonwealth countries which was key", she explained.
Meghan - who alongside Harry works as an ambassador for the Commonwealth Trust - had the flowers which represent all 53 countries in the Commonwealth stitched into her veil and she admitted it was very "important" for her to do that because of her new role.
"I knew that it would be a fun surprise as well for my now husband, who didn't know, and he was really over the moon to find out that I would make this choice for our day".
The touching reminder wasn't the only tradition the bride participated in on the day as her "something borrowed" came from the monarch herself. It was made in 1932, with the entire brooch dating back to 1893, according to Kensington Palace. "With the Duke and Duchess of Sussex about to embark on their first Commonwealth Tour to Australia, New Zealand and the Pacific exactly sixty-five years after the Queen's first Commonwealth Tour, this series could not be more timely". It's held in a different city every year.
In the clip, Meghan is reunited with her dress ahead of a new palace exhibit that will showcase the gown for public viewing.
Queen of the World will premiere on September 25 at 9:15 p.m. on ITV in the U.K. and on October 1 at 9 p.m. on HBO in the United States.
