In the Van Buren demo it works correctly. I can't prove it right now, but I sure remember that we are starting thr game wearing the prison suit. Anyone can download that demo and see it.
Indeed, it's work correctly in VB tech demo, I play it not long ago and textures looks like that :
Not my Pic but this is how suit looks like in VB.
Ps. Is the 3d graphics development tracker on wikia Up to date?
I can try to do some basic model if you want and textures for them.
