Well, not really, because I am, regrettably, much less familiar with Middle Eastern and Eastern history from that period than I am with the European, so I can't exactly say, "Oh, she should wear an outfit like a ____!" Especially since Faiza is Pakistani, and unless I'm even less informed than I thought, they weren't involved in the Crusades.
I don't know, maybe a modification of one of the outfits Saladin is often portrayed as wearing? (Google him.) I don't know how important he is in Pakistan's Sunni culture - he might just be a Middle Eastern hero.
