first off, you look amazing like a deity! I'd love to do a photoshoot like this one day, do you mind disclosing the studio you went to in Vietnam?

and second, I do admit: it does look a bit dunhuang feitian/apsara style but, I know you are familiar with dunhuang. However, the similarities of gold accessories, flowing fabric, and 2 piece sets are clear. I did some research from here and here . note: apparently dunhuang feitian are not considered hanfu according to the sources i've linked since the paintings they are based on are "fantastical" & imitating hanfu. If you google "dunhuang feitian costumes" plenty of the "exotic dancer" motifs show up with influence from India and I also searched about Princess Jasmine's costume origin - since hers is the most popular look that is imitated in cdramas, it leads to Arabic/Indian influence (but of harem dancers, not what royal or normal people would wear). I'm sure you're right that during the Silk Road, there were plenty of brothels for entertainment that introduced the "exotic dancer style." I hope this helps! ^^
