Personalised American Civil War Uniform

[figheadair]

I came across this fascinating example of personalised uniform worn by a Confederate officer photographed wearing a tartan jacket complete with his Captain's bars. I can't determine the tartan and it is likely he chose something that was fashionable at the time. I've never seen anything like this and assume that it must have been a personalised item that he wore to reflect his Scottish ancestry, perhaps he was even born in Scotland. I wonder how he managed to get away with it and how common such obvious departures from standardised uniform were at the time.
