Áo dài
In the 1950s, Saigon designers tightened the fit of the ao dai to create the version commonly seen today. Trần Kim of Thiết Lập Tailors and Dũng of Dũng Tailors created a dress with raglan sleeves and a diagonal seam that runs from the collar to the underarm. Madame Nhu, the first lady of South Vietnam, popularized a collarless version beginning in 1958. The ao dai was most popular from 1960 to 1975. A brightly-colored áo dài hippy was introduced in 1968. The áo dài mini, a version designed for practical use and convenience, had slits that extended above the waist and panels that reached only the knee.
