Vader is a
HOT costume to wear. Hence, I went with a lighter material to create my cape and under robe. I also went with a suiting material...it's light, breathes well and flows when you walk. All my gear is Portumac.
I want to say the satin lining, around the edge of the cape, came around during ESB(EPV)/ROTJ(EPVI). I don't think the SW(EPIV) Vader had a satin lining around the edge of the cape. I'm not totally positive the ROTS(EPIII) Vader had a satin lining around the edge of the cape either. The best scene to see the satin lining on the edge of the cape is in ESB(EPV) when Vader is speaking to the Bounty Hunters. There's a great snippet. Check it out. Notice I say satin lining
around the edge of the cape a lot.
Also, the hilt from the FX saber should suffice. I don't think this is one of those items the legion gets totally hung up on due to the small visibility of just a hilt hanging from the belt...unless it's a total frankenstein build.
I also have to agree with timbremer, I'm always stiff and sore after wearing Vader. I think it has to do with the constriction on the shoulders from the chest armor and of course; the huge, heavy ass bucket on top of your head.
Good luck with your quest, mate! Vader is a popular costume among all our fanbase.
