Much of the British public watched in admiration as Meghan Markle stepped out of the the car to enter Windsor Castle chapel to marry Prince Harry on May 19, offering the first glimpse of her stunning Givenchy gown with flowing train, designed by acclaimed British designer, Clare Waight Keller.

And now you can see the moment Meghan is reunited with the stunning gown for the first time since her big day thanks to a new ITV documentary, Queen of the World.

The two-part documentary, which was filmed over more than a year, will offer unique behind-the-scenes footage of Her Majesty The Queen and other members of the royal family, including the Duke and Duchess of Sussex, the Duke of Cambridge and the Prince of Wales. It will provide a sneak peek at the Queen's role as she hands down her duties to the new generation of young royals.

The trailer for the upcoming programme captures the moment Meghan is reunited with her wedding dress for the first time since the day she got married.

Smiling, she gasps looking at the dress's train: "Fifty-three countries, oh my goodness", she says, while touching the embroidered trim of the veil. "It'll keep us busy".

The duchess wanted to have all 53 countries of the Commonwealth with her on her wedding day, according to Kensington Palace, so Waight Keller designed a veil that represented the distinctive flora of each Commonwealth country united in one spectacular floral composition. At five metres long and made from silk tulle with a trim of hand-embroidered flowers in silk threads and organza, it's a masterpiece.

A spokesperson for ITV told the Standard that in this particular part of the documentary Meghan talks about the wedding day, the dress and the significance of having the 53 countries included in the design while the gown is prepared to go on display.

In another clip from the trailer, Prince Harry is seen talking candidly to young hospitality professionals from the Caribbean who were spending time at the palace for a new scheme led by the Queen. He said: "You guys have spent way more time in Buckingham Palace than I ever have and you’ve only been here two weeks.

"Have you bumped into the Queen yet?

"If you suddenly bump into her in the corridor, don’t panic. I know you will. We all do!"

The first part of Queen of the World airs on ITV on Tuesday September 25 at 9.15.p.m.
