Áo dài
The ao dai is now a standard for weddings, for celebrating Tết, and for other formal occasions. It is the required uniform for female teachers (mostly from high school and lower) and female students in common high schools in the South. There is no requirement for color or pattern for teachers, and students use plain white with some small patterns like flowers for their school uniform. Companies often require their female staff to wear uniforms that include the ao dai and so flight attendants, receptionists, bank female staff, restaurant staff, and hotel workers in Vietnam may be seen wearing it.
