Caraco, Casaquin

Two kinds of jackets worn at first only by the working class, later (1760/70s) adopted by the upper class.

Depending on the context and source, caraco and casaquin are different styles of jacket, or two types of the same garment in different styles, related like the robe à l'anglaise and robe à la française: Both had versions à la française and à l'anglaise, the difference being whether the pleats in back are loose or stiched to the lining.

Depending on the time of century, the jackets were thigh-length all around, or short in front with more or less gathered basques at the back.
