Purchased last year at a Christmas market in Germany. Made in Italy. 95% acrylic.
Never worn and never washed. Slightly stretchy and would be super comfortable. No exact size is available but would easily fit a XXL (looser fit) to a 2xl for a more bodycon fit. I would suggest washing on delicate cycle and lay flat to dry. Great for spring or fall. Add a turtle neck or chunky sweater and lined tights for a perfect winter outfit.

Measurements.
25" at the hips
36" long (knee length depending on height)
19" at the armpit
17" across the shoulders
