Two original outfits worn at the Queen's coronation and one of Her Majesty's own are set to go on display at Enniskillen Castle to mark the Platinum Jubilee.
A gown worn by Lady Moyra Campbell as well as an ensemble worn by Lord Erne at the ceremony in 1953 are set to go on display in the Co Fermanagh town.
While both have since died, their families found their carefully preserved garments from the special day in time for the jubilee.
Lady Moyra's son Rory described finding the dress at the family home close to Randalstown, Co Antrim. It had been stored under duvets to protect the delicate colours from sunlight.
The exhibition at Enniskillen Castle will opens today and is just one of a number of events taking place in Northern Ireland to mark the Platinum Jubilee this week.
