French Fly Breeches were worn1730-1770. They fit nicely at the waist and come to about 2 inches below the knee cap. At the knee they can button or buckle, on our lighter weight breeches they can also tie at the knee band. Our Men's breeches come with pewter buttons if you would prefer an antique pewter, brass or cloth covered we can add them on for an additional cost. In the back there is an open gusset that has a 2-3 inch give for weight fluctuation.
