"A long mantle of silk, velvet, cloth, or other material, worn by women, reaching to the ankles, and having arm-holes or sleeves." O.E.D.
"Out of doors on foot a lady met either dust or mud, and it behooved her to have her finery pretty well covered. The scarlet riding hood was efficient, and so many of them were worn that an English visitor saw them as the hallmark of American women. Another favorite outdoor coverall was the pelisse. It had full sleeves; it buttoned up to the neck; and it hung almost to the ground, all the way around. Not a thing of beauty, but it would cover almost anything." (Tunis 1957, p. 147)
