Fans of Princess Catherine
's iconic wedding dress
– nine-foot train and all – will soon have a chance to see it in all its glory.
The dress, designed by Sarah Burton at Alexander McQueen, will go on display when Buckingham Palace opens for tours from July 23 to Oct. 3.
The "whole ensemble" of dress, the Cartier "Halo" tiara, earrings, veil and satin and lace shoes will be on view, as will, over at the Mews, the Rolls-Royce Phantom VI and 1902 State Landau coach that carried Kate
to and from Westminster Abbey.
And inside the palace's State Dining Room: the magnificent Fiona Cairns's designed cake.
"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 at the Royal Collection. "There is a cut into it where the Duke and Duchess cut into it with a sword."
A spokesman for the couple tells PEOPLE, "The Duke and Duchess of Cambridge are delighted to give members of the public the opportunity to see, close-up, the skilled British craftsmanship that went into various elements of the wedding."
Kate chose McQueen "for the beauty of its craftsmanship and its respect for traditional workmanship and the technical construction of clothing," the Royal Collection, which runs the display, says in a statement.
Tour admission is about $28.70 for adults and $16.50 for children.
