Along with the wave of the modern ao dai, there is criticism about these transformation. People who want to reserve traditional value in the ao dai argue that the modern ao dai is miscellaneous. Mr. Duc Hung, Vietnamese famous designer, also raised his opinion about this issue: “I do assert that it is not the ao dai of Viet Nam. If we continue to advocate the trend of the modern ao dai, the traditional ao dai will be buried in oblivion…”. In spite of this, there are still a lot of favor from Vietnamese youngsters to the modern ao dai.
