Step-by-step explanation:
The jacket you are referring to is known as the Carmagnole. This type of jacket was popular during the French Revolution, particularly among the more radical members of the Revolutionary movement. It is often depicted in historical paintings as being made from a coarse material with wide lapels and metal buttons, and was typically worn with a red cap of liberty and a red, white, and blue cockade. The Carmagnole came to symbolize the anti-aristocratic sentiment of the French Revolution, as it was a style of clothing associated with the working class. History tells us that wearing the Carmagnole became a political statement in itself.
