 Traditional clothes are also often used to symbolize different regions.In women's attire, commonly the Áo tứ thân is associated with the North, the áo dài with the central region (due to its emergence in the Vietnamese royal court in the 18th century), and the Áo bà ba in the South (although many of these clothes are worn across different regions).However, the áo dài is now a very popular and widely worn ladies' attire nationwide.
