need to sew narrow panels together. The áo dài Le Mur, or "trendy" ao dai, created a sensation when model Nguyễn Thị Hậu wore it for a feature published by the newspaper Today in January 1935. The style was promoted by the artists of Tự Lực văn đoàn ("Self-Reliant Literary Group") as a national costume for the modern era. The painter Lê Phô introduced several popular styles of ao dai beginning in 1934. Such Westernized garments temporarily disappeared during World War II (1939–45). In the 1950s, Saigon (now Ho Chi Minh City) designers tightened the fit of the áo dài 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.

The áo dài was rarely worn except at weddings and other formal occasions, with the older, looser-fitting style preferred. Overseas Vietnamese, meanwhile, kept tradition alive with "Miss Ao Dai" pageants (Hoa Hậu Áo Dài), the most notable one held annually in Long Beach, California. The áo dài experienced a revival beginning in late 1980s, when state enterprise and schools began adopting the dress as a uniform again. In 1989, 16,000 Vietnamese attended a Miss Ao Dai Beauty Contest held in Ho Chi Minh City. When the Miss International Pageant in Tokyo gave its "Best National Costume" award to an
