What was Booth wearing?

[J. Beckert]

From Joseph Hazleton's statement.

"“I happened to turn my head toward the main entrance and saw Wilkes-Booth enter. He stopped a moment to say a word to Mr. Buckingham, the door-keeper, then started upstairs to the Dress Circle. As he passed along the side aisle toward the President’s box, I noticed the change in his dress. When he spoke to me in the afternoon he was dressed in the height of fashion…now he was wearing heavy riding boots, spurs, a blue flannel shirt and an army slouch hat. I wondered…what he was doing there on such a gala night dressed in such a garb."
