Are you referring to the old version with the pleated inner tunic and the longer outer tunic combined into one piece? The never version has the pleated knee-length tunic separate, and the longer outer tunic/hoodscarf over it correct? I've really only seen the new version on eBay. Because from what I've seen the XCoser only has 2 layers, where as the movie one appears to have 3 (check this thread for the layer references)

So while the newer XCoser version is more accurate layer wise than the first version, its still not quite screen accurate layer wise.
I'm guessing you contacted them with what I was thinking.....because the movie costume has 2 tunic layers that fall down to the wearers feet, it looks fuller than the current versions out there with only one layer of fabric down to the feet (because there is no real mid layer in these versions, just the pleated knee-length under tunic, and the outer tunic. No sleeveless non-hooded mid-tunic). Let me know how yours comes out....if they can add that extra mid-layer (or at least attach another long tunic bottom to fill it out, I will definitely wait and order than version.
