Fly Plaid at Burns Supper?

[figheadair]

The photo of the man wearing the military doublet troubles me somewhat. He is clearly wearing his chevrons on the wrong arm. Right arm only in that uniform. His sash and medals are correctly worn so it is not a mirror image. His friend clearly got dressed in the dark.
Hope I am not offending anyone but I do wish people would seek help when wearing unfamiliar attire.

There was a period (Crimea era) when NCOs and SNCOs wore their rank on both arms. It may be that that re-enactment uniform is supposed to represent that era and you're just not seeing the other arm/
