The modern ao dai turned up several years ago. However, the ao dai was a concern of people who need to wear it as a uniform such as: teacher, flight attendance, receptionists. It was not until the end of the year 2016 did the modern ao dai become so popular with hundreds of new designs. It is modified in the collar, the sleeves or the length of two flaps. Furthermore, instead of wearing pants with the ao dai, people nowadays prefer to wear culottes and skirts inside it. Not only the change in designs, people also use different materials for the modern ao dai like silk, brocade fabric or voile fabric.
