92% rayon/8% Spandex jersey jacket. Hangs open in front, and has additional fabric that creates a draping waterfall effect. Edges are cut clean and not hemmed; back is gathered in pleats and held in place with brass-toned studs. The sleeves are gathered into cuffs. Pit to pit measurement is tricky to get precisely because there are no seams from arm insets. And I estimate by how it falls that it's proportioned for about 22-23" pit to pit. It's about 23" long. In great condition.
