Yes, I think Vader probably had different capes on, at least in ESB.
OK, while we're still on the cape, you know how when Vader turns around and walks away from the camera we can see like a 2" trim on the end of the cape?
What is that?
Some have said that it's a leather piece attached, others have said it's part of the inner satin lining. I think it's the latter. In fact, I was going to just have the inner satin lining 2" longer than the outer wool layer, and maybe fold it over and onto the wool layer and sew it on. Would this be accurate?
Wookiee, regarding the layout of the cape, most of the websites dealing with this (eg., the 2 Vadermaker sites) advise that you cut out 6 isoceles triangles of 45 degrees (at the tip) each, sewn together at the isoceles sides so you have a 270 degree "pacman"-like cape.
But I found that this was way too much when I put it on my Vader, so I took out one of the 45 degree triangular pieces, leaving my cape to be 225 degrees, and this works about right. (See my site for my Vader. I can actually close up the cape more if I wanted to, but I preferred to reveal more armor.)
Regarding the codpiece, DJ, I think you might be referring to Dark Shadow (ickabel).
I note you said the codpieces had an indentation on the oval piece of about 0.5", but do you think some of the codpieces had no indentation and was level with the outside?
Look at this pic as an example:
Doesn't seem to be an indentation. I see this on other pictures too, and I actually prefer this look. What do you think?
