The history of the Vietnamese áo dài, from its 18th-century origins to the present day. From Lord Nguyễn Phúc Khoát and the modern Lemur reform to the áo dài of today.
The origins: Lord Nguyễn Phúc Khoát, 1744
The áo dài, Vietnam's national garment, carries a history deeply woven into the country's culture and politics. Historians trace its beginnings to the 18th century, during the Nguyễn lords. A pivotal moment came in 1744, when Lord Nguyễn Phúc Khoát (1714 to 1765), ruler of Đàng Trong (southern Vietnam), issued a dress reform that laid the foundation for what would become the áo dài.
The form we recognise today, a fitted tunic with two long tails and a pair of flowing trousers, was refined and more widely adopted through the Nguyễn Dynasty (1802 to 1945). During this era, the áo dài became the formal garment of the imperial court and educated classes.
Transformations through the centuries: from áo tấc to the modern áo dài
18th and 19th centuries: áo tấc and the Chinese influence
In its earliest form, the Vietnamese áo dài carried traces of Chinese court dress, particularly the qipao of successive Chinese dynasties. Vietnamese tailors, however, shaped their own version. The áo tấc held the body closely at the chest, waist and hip, paired with long trousers covering the legs. Its defining feature was its pair of split tails, opening from the waist downward, one in front and one behind.
This distinguished the Vietnamese áo dài clearly from the Chinese qipao (typically without split tails), reflecting both practical needs and a distinctly Vietnamese aesthetic. The 18th and 19th century áo dài was most often crafted from mulberry silk, brocade or other premium fabrics, with hand embroidery reserved for members of the imperial family and the upper class.
Early 20th century: the Cát Tường and Lê Phổ reforms (1930s)
The early 20th century saw a rapid reimagining of the áo dài. In the 1930s, during the French colonial period, Vietnamese designers began adapting the áo dài to meet modern sensibilities while holding onto its cultural identity. Designer Cát Tường (known in French as Le Mur) led this modernisation in 1934, introducing a more contemporary cut with simpler sleeves and a softer silhouette. Designer Lê Phổ later refined the form with a more body-fitting line.
These reforms brought distinct changes. The silhouette became closer to the body, the tails were cut higher for greater ease of movement, and the garment honoured a softer, quietly feminine presence. The reformed áo dài gained rapid popularity through the 1940s and 1950s, particularly among educated women and middle-class families in Saigon. It represented a refined meeting of tradition and modernity, and it established the foundation for the áo dài of today.
1960s to 1970s: the Raglan áo dài and the settled modern form
In 1960s Saigon, the áo dài evolved further with the introduction of the Raglan sleeve, creating a cleaner line from shoulder to arm. By the 1970s, the form had largely settled into the silhouette we recognise today.
After 1975: decline and return
After 1975, with national reunification under the socialist government, the áo dài entered a difficult period. The revolutionary aesthetic of the time did not favour traditional dress, and the áo dài was seen as a garment of the former order. Its use was limited to formal ceremonies and particular circumstances.
Beginning in the 1990s, as Vietnam opened its economy and re-entered the international community, the áo dài returned in force. A renewed sense of national pride, and a desire to assert Vietnamese identity to the world, drove its return. From the 1990s onward, the áo dài reappeared not only in diplomatic settings but also as a symbol of national pride at international events.
The modern áo dài: from the 1990s to today
Today's áo dài develops along two parallel paths: preserving tradition, and opening toward new creative expression. Contemporary designers combine the traditional structure, a fitted tunic, split tails, and long trousers, with new fabrics, modern palettes, and refined design details.
Tailors and designers such as La Hằng (who founded La Hằng Design in 1992), Võ Việt Chung, and a generation of younger designers have guided the áo dài into contemporary life. Experiments with new fabrics (cotton-silk blends, refined linens) and palettes aligned with global fashion trends have unfolded alongside a steady commitment to the áo dài's essential identity.
In recent decades, the áo dài has returned as an everyday choice for some younger women, worn beyond formal occasions. This shift speaks to a strong revival of tradition, and a reminder that cultural preservation is not a matter of the past alone but a living, unfolding process. Vietnamese speak of this moment as "đường đua áo dài", a return of the garment among the young.
International recognition: the Oxford English Dictionary
A significant moment in the áo dài's history came with its international recognition. The word "áo dài" entered the Oxford English Dictionary, marking its status as a globally recognised Vietnamese word. It is one of only three Vietnamese words that have entered the dictionary, alongside "phở" and "bánh mì". The áo dài has moved beyond the boundaries of Vietnamese culture to become part of the international vocabulary.
Major international organisations have also recognised the áo dài's cultural significance. UNESCO and other heritage bodies have noted its importance to Vietnamese and world culture, though the áo dài has not yet been formally inscribed on UNESCO's list of Intangible Cultural Heritage.
The áo dài as Vietnamese cultural heritage
The áo dài is more than a garment. It is a symbol of Vietnamese cultural heritage. Every element of the áo dài, from construction to fabric to colour to embroidered motif, reflects the values, ideas and lived experience of the Vietnamese across the centuries.
The áo dài has built a global image of the Vietnamese woman: refined, gracious, and quietly considered. It holds close ties with many Vietnamese traditions and values: respect for one's parents, a love for one's ancestors, and a devotion to country.
To preserve the áo dài is to preserve a meaningful part of Vietnamese cultural heritage. Each Vietnamese person, in choosing to wear the áo dài, participates in keeping this heritage alive and letting it grow. In more than 30 years of work, La Hằng Design has held this as its own responsibility, to preserve the traditional craft of áo dài tailoring while allowing the garment to move with its time.
Áo dài trends for 2026 and beyond
Through 2026, the áo dài continues to evolve alongside a steady return to tradition. Notable directions include:
- Contemporary palettes: soft violet, blush pink, earth tones of yellow, or metallic silvers that carry a modern presence while holding a refined grace.
- Material combinations: traditional silks paired with modern fabrics such as premium cotton, linen, and more sustainable fibres, aligning the áo dài with global trends toward more considered fashion.
- Refined design details: lighter shoulder construction, subtle adjustments to tail proportion for a contemporary silhouette, and new embroidery techniques used alongside (not in place of) traditional handwork.
- Casual áo dài: the emergence of lighter, simpler áo dài for less formal occasions and even everyday wear, speaking to the áo dài's return to daily life.
- Honouring handcraft: a renewed focus on traditional hand embroidery and hand tailoring, reflecting a wider cultural appreciation for the value of craftsmanship.
The áo dài in the future
The áo dài will continue as one of Vietnam's most meaningful cultural symbols, particularly as the world grows in its appreciation of cultural diversity and heritage. Younger generations of Vietnamese, connected to the world through the internet and social media, have found new ways of expressing pride in their national heritage. The áo dài, with its timeless grace, remains a meaningful way of doing so.
The journey of the áo dài, from the 1700s through to 2026, reminds us that cultural heritage is not something static or unchanging. It is a living process of adaptation, creativity, and honouring what has come before. To preserve the áo dài is to let it continue to unfold, and to let new generations find their own ways of wearing and honouring it.
Frequently asked questions
1. When did the áo dài first appear?
The áo dài has predecessors from the 16th to 18th centuries, long tunic-style garments worn across Vietnam. The áo dài as we know it today, with its defining features (fitted tunic, split tails), was refined and formalised in the 18th and 19th centuries under the Nguyễn Dynasty. The 1930s reform led by Cát Tường and later Lê Phổ created the modern silhouette that still defines the áo dài today.
2. Is the áo dài UNESCO-recognised heritage?
The áo dài is widely recognised internationally as cultural heritage worthy of preservation. The word "áo dài" has entered the Oxford English Dictionary, a mark of its global recognition. The áo dài has not yet been formally inscribed on UNESCO's list of Intangible Cultural Heritage, though recognition from other international bodies and from the broader public has established its cultural significance.
3. How can we preserve the áo dài for future generations?
Preservation works at several levels: teaching younger generations about the history and meaning of the áo dài, continuing the traditional handcraft (hand tailoring, hand embroidery), supporting the tailors and designers who carry the tradition, and allowing the áo dài to continue evolving. Wearing the áo dài in everyday moments, not only for major celebrations, is itself a way of keeping the tradition alive.
