The ao dai is now most commonly worn by women. In its current form, it is a tight fitting silk tunic worn over pants. The word ao dai was originally worn at the court of the Nguyen Dynasty at Hue in the 18th century. This outfit evolved into a modern dress in the 1920s and 1930s. This updated look was promoted by artists and magazines as a national costume for the modern era. In the fifties, Saigon designers tightened the tunic part to produce the version worn by Vietnamese women today. On Tet and other Vietnamese holidays and occasions, Vietnamese men may wear an ao gam brocade robe, a mens version of the ao dai, made with less bright colors.
