It's been four months since former actress Meghan Markle and Prince Harry tied the knot, and their wedding is still one of the most talked about occasions of 2018.

There were plenty of details about the royal wedding that were revealed to the public in the months and weeks leading up to the big day and on the day of the event too, but there's still so much we were not aware of.

In the new documentary about Queen Elizabeth II, Queen of the World, the Duchess of Sussex shared some interesting facts about her wedding attire, specifically her iconic veil.

Meghan revealed that Harry had no idea she was going to have flowers from all 53 countries of the Commonwealth embroidered on the veil. She wanted to pay tribute to the Commonwealth as well as her new family.

"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 together," explained the new royal.

But this wasn't the only surprise Meghan's veil, which was designed by Clare Waight Keller of Givenchy Haute Couture, was holding.

Somewhere within the folds of the 16.4-foot fabric was a piece of blue fabric, which served as her something blue as well as a sweet nod to her prince.

Turns out, the cloth scrap was from the dress she wore on her first date with Prince Harry. Aww!

"Somewhere in here there's a piece of . . . did you see it? The piece of blue fabric that's stitched inside? It's my something blue," the duchess says in the film. "It's fabric from the dress that I wore on our first date."

Although the couple has never bothered to comment on the details of their first date, it is believed that they were set up on a blind date by a mutual friend. They reportedly met at the London branch of the exclusive members-only club, Soho House, and the rest was history.

Other elements of Meghan's wedding outfit ticked off the rest of the boxes for something old, something borrowed and something new. The Queen Mary's Diamond Bandeau tiara, which the Queen lent her, dates all the way back to the 19th century and her wedding dress was her something new.

As for the documentary, which "focuses on The Queen's role as Head of the Commonwealth and reveals how it has been a central focus and passion throughout Her Majesty's life", it airs in the U.K. this week, but over the pond, royal watchers will have to wait until October 1st when it premieres on HBO.
