Princess Diana's iconic wedding dress goes on display for the first time in 25 years

The dress that Diana, Princess of Wales, wore on her wedding day with Prince Charles in 1981, has gone on display at Kensington Palace for the first time in 25 years.

Princess Diana's wedding dress for her 1981 marriage to Prince Charles was one of the best-kept secrets in fashion history. The gown sparked such intense interest that young designers David and Elizabeth Emanuel locked the ivory silk dress, which had a 25-foot (7.6-metre) long train, in a safe at night. Plucked from obscurity for the commission of a lifetime, the pair even took to putting dummy bits of fabric in the studio's bins to throw anyone rummaging through them off the scent, according to an exhibition of royal fashion, including Diana's iconic dress, that opens on Thursday. The exhibition - Royal Style in the Making - at the Orangery at Kensington Palace, Diana's home until her death in a car crash in Paris in 1997, focuses on the work of designers who dressed not just Diana but also Queen Elizabeth II, Princess Margaret and the Queen Mother.
