Even though I am new here, I have been in uniform for more than 22 years. I have to say that I agree with this. These are basic items that this costume should have. I have been waiting on my armor to arrive from KS for a while now and have taken that time to get everything in order that I can. Including sewing the patches on my flight suit and beginning my vest. I have no interest in going Lancer but I that is only because I think nylon straps and non carved boot soles look fine. And my only argument there is that uniform items evolve and change, even in the Empire (hence different looks of tk's for different movies) and I have seen a lot of small differences over the years in uniforms that were still acceptable. But I will say that I don't think anyone would go out without protective gear such as a flak vest in combat (too many pesky rebels out there for that). So why not make sure it is part of your costume? It does look good and I imagine helps with the shoulder bells fitting properly for those of us who are smaller in stature.
Anyway, sorry for the rambling but this is just my opinion and I say well done.
