From a fascinating exhibit at the Los Angeles County Museum of Art, “Fashioning Fashion: European Dress in Detail 1700-1915.” These are the actual clothes worn at the time, not reproductions.
Aristocrats who opposed the French Revolution while it was happening wore deliberately elegant clothes, that flaunted their wealth and thus expressed contempt for the revolution, as in the first photo.

Partisans on both sides carried the huge canes, known as Hercules clubs, to ward off attacks.
