Throughout the S-shaped strip of the land of Vietnam, Ao dai can be found in every region. Specifically, in Hue, Ao dai has become a part of the cultural identity and unique beauty of the people here. An important milestone in Hue Ao dai costume was in 1744, after Lord Nguyen Phuc Khoat ascended the throne in Phu Xuan, he promulgated many policies and mentioned the modification of costumes. Thereafter, during the Nguyen Dynasty, the court issued an order, creating an opportunity for Hue women in particular and Vietnamese women in general to wear Ao dai regularly. Accordingly, the tradition of wearing Ao dai gradually entered the daily life of people.
