I trimmed the return edge off the front yoke, so there a curvature and sense of depth to the plastic on the back piece, but not on the yoke. The plastic is "flat" from the front of my shoulder for about 6 inches under my armpit.
I am at an impasse. I can get a replacement piece, but it's kind of a hefty cost. I don't want to try to attach the back to the yoke, because doing do would probably destroy the back and if I have to replace it, it's two pieces.
Suggestions? Is the costume approvable without the return edge? And even if approvable, will it look good? I don't want to half-an impolite person it.
