Kate Middleton McQueen wedding dress on display.JPG

The dress that captured the world only a few months ago is set to go on display at Buckingham Palace for the annual summer exhibition this year. Kate Middleton's breath-taking Alexander McQueen gown has already attracted record sales in advance tickets, which have more than doubled from last year's summer opening. Over 600,000 people have paid £17.50 per ticket to have a first-hand look at the dress over the next ten weeks.

Visitors will also get to see the Duchess of Cambridge's wedding shoes, also by McQueen (she's a size five and a half) and the royal wedding cake. The exhibition's curator, Caroline de Guitaut, revealed that the couple have kept the top two layers of their wedding cake, which is traditionally used as a christening cake for a first born child.

The Royal Wedding Dress: A Story of Great British Design runs until October 3 at Buckingham Palace. Tickets are available from www.royalcollection.org.uk
