So, I did some digging on the Imperial Officer forums, and there has been some discussion on this character but not much action. I am working with CosplaySky on the properly modified white tunic with a fusion of standard and ISB style cues in his tunic. Specifically, while the yoke is cut in the ISB style, the yoke is also not as wide so it reveals the right side pocket and it also has a left side pocket. ISB tunics do not have the pockets. Otherwise, it will be the same as a standard black tunic with the yoke cut differently. It will not go up to the right shoulder. Picture from game for reference.
I'm ordering a couple of extra yards of trouser material for a hat or 2 to be constructed likely by Tigg-Wolf, who is also making the rank bars.
His belt buckle is flat not curved, but if my current curved buckle belt from Brian Pfau will pass for basic approval, I will stick with that for now.
Need gloves and boots still but this will come together fairly quickly, and if it looks good enough, maybe I can be the CRL model?
Wish me luck.
