I'm working on the costumes. I found a pattern to use for the tops that won't take much modification at all.
Kwik Sew 4032 is for a fleece jacket, but it already has the blocking in the pattern for the various colors of the uniform (gray collar and shoulders, main color front and back, and black sides). All you need to do is trim it in for a better fit, leave out the pockets, and add piping and the shoulder ranks. I'm planning on making the ranks from EVA and securing them with a thin, strong grip velcro. The bottoms appear to be a simple slacks pattern with thin piping matching the color block of the upper uniform.
I have tried contacting the costume designer through his agent to get information on what the mesh-like color pieces of the uniforms are made of, but while the agent responded quickly (and positively) and promised to forward my email, I have not yet heard back from Porro himself. Since it's been over a month, I'm not optimistic that I'll actually hear back from him.
So, if anyone can identify the textured mesh that the costumes are made of, I would LOVE to be able to get ahold of some. I've searched all the meshes I can find on the internet, but they don't have the right mix of horizontal lines and hole pattern.
Here's a real high res pic of one of the uniforms that really captures the odd mesh.
