In this undated photo released by the Royal Collection on Thursday April 21 2011, a conservator puts finishing touches to the simple but stunning wedding dress worn by HRH Princess Margaret when she married Lord Snowdon in 1960. The glamorous dress comprised a fitted bodice and a full skirt of fine diaphanous silk. As speculation continues as to the design of Catherine Middletons wedding dress, a precious collection of historic royal wedding dresses worn by royal brides over the last 200 years have just undergone over 1000 hours of conservation treatment by conservators from Britain's Historic Royal Palaces. The wedding dresses belonging to Princess Charlotte (1816), Queen Victoria (1840), Alexandra of Denmark (1863), Princess Mary of Teck (1893), Princess Margaret (1960) and Princess Alexandra of Kent (1963) are usually carefully stored at Kensington Palace but have been made available to the media and are viewable on the Historic Royal Palaces website.
