Solid Color Kilt in "Mrs. Brown"

[Planopiper]

Notice that Mr. Brown also wears a horsehair sporran. I believe I've seen at least one other portrait with him wearing a white horsehair sporran. We don't do that much now, but the precedent for wearing one with non-military dress is there.

He also wore a glengarry, which is unusual when it's not part of a uniform. He may have been in the military and kept it from the old days. Not many people can pull it off with non-uniform dress, though.
