Hello Magazine say that HMs gown and robes will be on display. Here's their text


Alongside the delicately small outfits, the Queen's satin gown will take prize position. The white Norman Hartnell garment will be joined by the twenty-one foot robe and jewels that adorned the monarch on her special day.

This will be the first gathering of her ceremonial clothing since the event took place. Curator Caroline added: "The 60th anniversary of Her Majesty's Coronation provides a marvellous occasion to exhibit these charming clothes alongside the grand dresses and robes of the Royal family.

"The children's outfits help to remind us of the Queen as Sovereign and, at the same time, a mother of two young children."
