The dress, designed by Sarah Burton at Alexander McQueen, will go on display when Buckingham Palace opens for tours from July 23-October 3!
The whole ensemble of the dress, the Cartier "Halo" tiara, earrings, veil and satin and lace shoes will be on view, as will other Royal Wedding items.
The Rolls-Royce Phantom VI and 1902 State Landau coach that carried Middleton to and from Westminster Abbey will also be on the grounds.
Inside the palace's State Dining Room, the magnificent Fiona Cairns's designed cake will even be available for the public's viewing pleasure.
"Other cakes were made to serve to guests, but the one that was cut by the royal couple is the one that will be on display," says a source.
"There is a cut where the Duke and Duchess cut into it with a sword."
Sounds awesome! As for the dress, Kate chose McQueen "for the beauty of its craftsmanship and its respect for traditional workmanship and the technical construction of clothing," the Royal Collection says in a statement.
