Lots of kilts at our Dickens on the Strand fest last year. Since the dress tends to be late 1800's Victorian formal, most were worn with PC jackets and blak tie, like a Burns supper was about to break out! I think an Argyll and waistcoat, with period shirt and neckwear is more "authentic" for the period. Not sure about deerstalkers, but do have a hat, everyone wore hats in those days.
