From the reference picture my take on it was that I couldn't see a shoulder seam, no collar, no fastenings and that strange double layer at the shoulder. I actually threw out the question on Facebook on the issue with the layers of fabric could be, and I got an answer from Kathy that it looked like the kind of shoulder tuck that you also find on jedi tunics and X-wing pilot jumpsuits. So went to the Rebel Legion forums and read up on a couple of jedi tutorials to figure out what the tuck was, and then I started on the vest.
I had ordered 1 m of black, heavy twill. The fabric was a pretty good match I think, but I should have ordered more so I could have self lined it, still this is just an experiment and I'm counting on having to redo quite a lot when we get proper reference pictures.
This is probably the best picture of the vest, when me and Björn tried to recreate the trailer shot.
I will try to show how I made the hairstyle as well later on.
