The RAF marked its centenary with a spectacular sky-procession, as some 100 planes, old and new, performed a massed fly-past up the Mall in London and over Buckingham Palace, watched by the Queen and members of the royal family alongside at least 70,000 spectators.
The dress features an nearly identical open-shoulder neckline as her Givenchy wedding gown, and has a strikingly similar silhouette.

Meghan's messy bun was her thing.
For the occasion, the Suits alum wore a bespoke dark navy Dior dress that featured a boatneck and full skirt.
"I hope he stays like this", Middleton told the archbishop of Canterbury, the Rev. Justin Welby, who baptized Prince Louis in the Chapel Royal at St James' Palace.
Meghan's elegant dress was by Dior. She paired the look with a gorgeous brooch, a matching Sean Barrett hat and nude heels.
The event also marked another stop in what is a very busy itinerary for the newlywed royal couple, who will fly to Dublin soon after the celebrations, where as well as attending meetings with Irish President Michael Higgins and Prime Minister Leo Varadkar, the royal couple will visit the home of Gaelic football and the country's most popular university.
The queen, dressed in a royal blue outfit with turquoise edging, later hosted a ceremony to present the RAF with a new Queen's Colour, at which she recognised the service's work.
She was unable to attend the christening of Prince Louis of Cambridge on Monday, as she was travelling, but paying homage to Britain's military services is one of her most important roles as monarch.
Harry and Meghan later joined royals at a Buckingham Palace reception to mark the centenary of the Royal Air Force.
