Orientalism and the Age of Steam is doing a multi-part series on recreating Elamo-Persian royal women's dress.  Anyone wishing to reenact as such should check it out.  Currently parts one and two are up.

Word of warning - even though Orientalism and the Age of Steam's title banner is just a 19th-century Orientalist painting, let's just say those 19th-century Orientalist paintings could get pretty NSFW.

Thanks also to these articles for alerting me to Saudi Aramco's Millennia of Murex article, where you can see a beautifully-preserved example of authentic Achaemenid-period Persian patterned cloth.
