I just thumbed through my copy of Dressing A Galaxy. The sleeves on the outer robe were cut separately from the body, and left open at the front for movement of the arms. Also, the OT and the Prequels had a slight variation on the front of the robe. The OT version was fuller at the front and featured a "cowl neck" look. The newer version is flatter, and has a trimmer look to it. Both were made from a low-pile non-stretch velvet. The under robe is long sleeved and made from the same burgundy silk used to line the outer robe.
