The Queen’s most recognisable frock will be on display Buckingham Palace.
The stunning exhibition, that ties into her 90th celebrations, titled Fashioning A Reign: 90 Years of Style from the Queen’s Wardrobe, will open to the public from July 23.
And the palace has just given us a sneak peek!
This is the second time the Monarch’s most-treasured outfits from her childhood to the present day has been exhibited.
It will “show the unique requirements of royal couture” with a mix of historical items including iconic designs from Sir Norman Hartnell and Sir Hardy Amies.
Royal watchers will recognise her sunshine yellow coat that she donned at Wills and Kate’s 2011 nuptials.
And of course, fans of Britannia’s longest reigning monarch would be delighted to see her favourtie glittering ballgowns.
One majestic item on display is a turquoise silk shift dress with silver floral embroidery by Hardy Amies.
It was worn by the Queen for an official portrait by Cecil Beaton in the White Drawing Room, Buckingham Palace, 1968.
While the other glittering gem on show is a pale blue and gold evening dress worn on a state visit to the Netherlands in 1958.
With a full arc of her life through her fashion, avid royal watchers will get a chance to see other historical items, including her uniform that she donned when she was Princess Elizabeth.
Just a teen, the royal proudly wore it while serving in the Auxiliary Territorial Service (ATS) during the Second World War.
The exhibit will highlight some of the most prolific moments in Her Majesty’s life.
It will no doubt shine a light on the splendours she has experienced through her 64-year-reign.
The Queen’s official residences will host three separate displays marking her 90th birthday – with a total of around 150 outfits to be shown at Buckingham Palace, the Palace of Holyroodhouse in Edinburgh and at Windsor Castle.
We think that sounds absolutely grand!
