I think what YehudahTzvi is saying is quite reasonable that the traditional ME clothing is probably very similar to what was worn 2000 years ago. BUT I do realize that styles change. They could have changed from then until now, and even if the did not, we could still wear our western/European clothes now.
Speaking of Iraqi Jews, the Ben Ish Hy mentions not to wear black on Shabbat, but IIRC he does not mention any style. Furthermore, the Mishnah of Shabbat 6th perek talks about different styles of clothing. Apparently there were different styles back then.
