I found 2 images made with AI but well done. Below I'll leave some pictures of Hollywood.  One is an Arab woman and the other a Bactrian princess. This is a character from the series The Chosen who has good advice regarding clothing. As always, Hollywood has its problems with armor; sometimes, for safety reasons, they don't use realistic armor. It seems that Middle Eastern and Central Asian cultures liked those hanging ornaments.

I found an interesting image of an art based on a fresco and relief with AI. Below I will leave other references that are unclear but seem convincing. 

Oops! You are certainly right! Sorry for the confusion!

These clothes, it seems to me, resemble those from Central Asia and Hellenized areas of India.  Hellenistic India. Kushan art. The trousers bear a certain resemblance. Probably an influence from Iranian peoples.

Women generally wore a tunic, a mantle fastened on the left shoulder with a fibula, earrings, one or more necklaces, bracelets, a brow band often decorated with plant motifs, a turban and a long veil. A preference for an Iranian garment or a Greek mantle was a matter of taste, wealth or mood, not of origin or profession. The central role played by Palmyra in trade between the Mediterranean and the East made it one of the main stopping points for caravans transporting luxury materials such as gold, gemstones and pearls. It was also a focal point for the styles, fashions and techniques that travelled with the merchants. The Palmyreans assimilated these different influences: Palmyrene silverwork and goldwork, for example, are a rich synthesis of eastern, Roman, Greek, Hellenistic and Syrian elements and motifs.
