If you look at the two pairs of pants in the two photos they are not the same pair of pants, look at the strips by the zipper on both pairs they do not line up the same.
A lot of twitter posters came to that same conclusion last night. That little guy wearing those plaid pants, however, is the exact same height and build as the guy in the KKK costume.(5’6” or so) assuming northman in blackface(he’s 5’11”—?)
