More on the French Froc/Frock

French reversible men's Frock 1750-1762.

French woman's robe. 1750-1762

I found this full image of the 18th century French peasant family.

French burial detail of peasants on the field of battle. No date. All are wearing frocks and wooden clogs. Judging by the trousers on the peasants and the bodies, I would say this is 19th century.

The Common Frock Versus The American Revolution Frock.

There are variations in frock styles, but the most common are the Shirt Frock 1680-1830, and the Hunting Frock 1770-1780.
These dates are not exact, the Shirt Frock started to appear Pre 17th Century and was still in use in the early 20th century in a Frocked form.
The Frilled Hunting Frock did not exist as far as I am able to tell before the American Revolution, and did not appear to be as popular as the European Shirt Frock, not is there any evidence that it remained in use for very long after the Revolution period.

The Common Shirt style Frock worn in Europe 1680-1830.

The American Revolution style Frock. Open fold over front, 1770-1780.

I welcome any more documented information on these Frocks.
