Also note, armor is ROTS, and helmet… maybe an ESB with ANH colors. Again, not a Vader purist.
Overall things are looking pretty good.
There is nothing on the armor suggesting it’s ROTS. The OT chest armor was three pieces: one for the chest and two separate shoulder pieces. ROTS had this single unsightly piece that included the chest and shoulder armor all together. The shoulders here are covered by the cape, so at this point it’s unclear what the armor is.
The outer robe here is worn under the armor, as it was in ROTS, TESB, and ROTJ. I can understand why they made this change, as Vader simply looks more aggressive with the armor on top of the robe.
The chest box is accurate to ANH (and ROTS) since it has the green button.
The helmet is a little hard to make out. The true calling card of the ANH helmet is the widow’s peak. I think I can vaguely make one out here, but it’s hard to be sure.
