Officials say the dress designed by Sarah Burton of the Alexander McQueen fashion house will be displayed from July 23 until Oct 3.
Royal collection officials said Monday that the veil, tiara, wedding shoes and diamond earrings Middleton, now the Duchess of Cambridge, wore on her wedding day to Prince William will be part of the special exhibit.
The wedding display will be part of a popular tour of some of the palace's state rooms offered to visitors during the summer months. The tour includes a chance to see some of the queen's formidable art collection including works by Rembrandt and Rubens.
The tour of the state room typically costs 17.50 pounds ($29).
