In advance of an exhibition of Wedding Dresses in 2013 London's Victoria and Albert Museum is creating a database of photographs of clothes worn for weddings from all cultures between 1840 and the present. This includes civil partnerships. This database will provide a rich record and help people date their own photographs. The museum is inviting people with images to upload them.
To ensure it builds a useful historical record all entries will provide the year of the event and the names of the bride and groom or partners. The place and the religion of the wedding will be included if possible. More details and the site are here: http://www.vam.ac.uk/things-to-do/wedding-fashion/home
