Overview
In the Later Le, which made Confucianism the state norm, official dress codes were ordered and colour and pattern assigned by rank.
Key garments and style
The court and officials wore the cross-collar robe with cap and belt. In the 18th century, Lord Nguyễn Phúc Khoát, who ruled the south, promoted a front-fastening, buttoned five-panel gown (áo ngũ thân) — the ancestor of the later áo dài. Women in the north wore the four-panel dress (áo tứ thân).
Transition
When the Nguyen dynasty unified the whole country, this five-panel gown spread as a national dress.
