Has anyone noticed that the robe which Obi-Wan is seen wearing in ANH is significantly different from the robes seen on jedi in the PT? In paticular the beige inner robe is longer and there is a brown undershirt as opposed to the layered v-necks in the PT. I first postulated that perhaps Obi-Wan chose to wear a different robe in order to further his disguise when he went in hiding, but I later noticed that the ghost of Anakin wears the same robe in ROTJ implying that this is the standard Jedi garb. As much as I love the elegant robes designed for the PT, this inconsistency between the designs has always irritated me. I'd love to hear some other theories on this.
