There isn't a lot of authentic Middle Eastern stuff even for V3, who's been out a lot longer. Your best bet may be to use Steph's Morphing Fantasy Dress. You can probably use a shawl/veil made for V3 with a little tweaking. (There was a thread here earlier about using the P5 Cloth Room to fit V3's clothes to Steph.) I've found nun outfits work for Middle Eastern clothing. The Penny Dreadful outfit, for example. (I know, I know. But the veil from that package really does work well for Biblical era costumes.)
