This is a J. Jill Wearever 3/4 Sleeve Midi Dress that is a size Large. It is 95% Rayon and 5% Spandex. Laying flat, it measures: Armpit to armpit-21.5" and the length is 39.5". It is very soft and in great condition. Please measure something that fits you laying flat. The length is measured from the shoulder to the bottom hem.
