An item that Queen Victoria may have preferred kept a secret has been added to Britain's Royal Ceremonial Dress Collection at Kensington Palace.
The item in question is a set of bloomers with a 56 inch (142 cm) waist, a matching chemise and the letters "VR" - Victoria Regina - embroidered on them. They are believed to date from the 1890s.
The bloomers were purchased by the collection for £600, earlier this summer.
It was likely that they were passed on to a servant after the monarch's death, according to curator Alexandra Kim.
Overall, 12,000 items feature in the collection at Kensington Palace, in London. It includes photographs, prints, sketches, diaries and famous outfits.
