Costume progress.
After some thought on the matter I decided to slip a couple of (very small) shoulder-pads into the Junior Warrant Officer Schrödinger shirt.
Some people have strong opinions on shoulder-pads, saying that they should not be used if you are feminine or have poor posture because all they really do is end up drawing attention to the fact, but if that were true then only male body-builders would ever bother getting a nicely tailored suit.
