The mid coat definitely has pin-tucks, it's even more clear in this pic: http://i.imgur.com/dZ24GpD.jpg
But, at least at that part of his costume, the fabric is very clearly separated from the sleeves. I talked about this last night with a 501st member who got to see the costume in person, she insists it's a separate garment of separate material, but agrees that it's definitely got the pin tucks in it. I've never wanted more high def image of a sith's armpit before....
They are definitely separated, but they appear to be the same fabric, or at least very very similar.
If they are different fabric, it could easily be that wool you pointed out. I'm a little worried the 501st isn't going to release the costume requirements until the movie is out, which means I may need to just resign myself to sewing it twice.

I tried upping the image resolution for the boots reference image using Similia Enlarger. Hope this helps.
I also think jamesrt1 on Photobucket did a good job (albeit the belt strap placement is a little off and it's not as lustrous):

Also, does anyone else see the resemblance of Kylo Ren's and Anakin's boots? Maybe it's just the straps, but it feels as if there's something more to this.
