The wedding dress of the American actress Grace Kelly, worn during her wedding to Rainier III of Monaco on 19 April 1956, is cited as one of the most elegant and best-remembered bridal gowns of all time, and one of the most famous since the mid 20th century. One author describes the dress as a symbol of "the marital fervor" and a major influence on women who strove to "emulate Kelly's peau de soie and lace masterpiece". It was designed by Helen Rose of MGM. The dress consisted of a bodice with an attached under-bodice and skirt support. There were two petticoats, one being an attached foundation. The wedding attire included a headdress, veil, shoes and the lace- and pearl-encrusted prayer book which she carried down the aisle. To celebrate the 50th anniversary of the wedding, the Philadelphia Museum of Art displayed it at the museum between 1 April and 21 May 2006 and reported it to have been arguably its most popular exhibit.

A wedding dress or bridal gown is the dress worn by the bride during a wedding ceremony. The color, style and ceremonial importance of the gown can depend on the religion and culture of the wedding participants. In Western culture, the wedding dress is most commonly white, a fashion made popular by Queen Victoria when she married in 1840. In Eastern cultures, brides often choose red to symbolize auspiciousness.
