Watch Meghan Markle Reunite With Her Wedding Dress

Meghan Markle is getting used to living her life in the world's brightest spotlight, and she's decided to share a very special moment with royal watchers as part of a new ITV documentary on Her Majesty called Queen of the World. In a new trailer, the Royal Family's new member can be seen having an emotional reunion with her spectacular Givenchy wedding gown and veil as it's prepared for an upcoming exhibition. "Fifty-three countries. Oh my goodness. It will keep us busy," she says in the clip.

The Duchess of Sussex famously had her silk veil embroidered with floral emblems from all 53 Commonwealth countries, showing her dedication to the organization of which Prince Harry's grandmother is head and he is the newly minted youth ambassador. The 16-foot-long piece also featured two personally meaningful blooms: wintersweet, which grows around her Kensington Palace home, Nottingham Cottage, and the California Poppy, paying homage to her birthplace and former home.

One of her husband's scenes in the film is quite comical as he reveals his nerves around his granny, who granted special access to her family over the course of a year as ITV filmed the series. As he welcomes a group of hospitality professionals from the Caribbean, Prince Harry jokes about crossing paths with her. "You guys have spent way more time in Buckingham Palace than I ever have and you've only been here two weeks!" Harry says. "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!"

Duchess Kate also features in the two-part series, which shows how the monarch is passing her dedication to the Commonwealth to the younger generation. The mother of three's scene is a timely one as it explores her last trip to London Fashion Week, when she and the Countess of Wessex hosted an event at Buckingham Palace to celebrate designers from around the Commonwealth with a special exhibition.

Another scene will see the Queen having to stop recording her Christmas address, which is interrupted by the sound of birds outside. The special airs on HBO on Oct. 1.
