Benetton Forest Green Crocheted Long Cardigan Sweater Women’s size Medium

Very gently used - Benetton Forest Green Crocheted Long Cardigan Sweater Tags have been removed so I’m guessing that this is a women’s size medium 33.5” Long from back neckline x 20” wide from pit to pit; sleeves are 21” Long Flaws- there are belt loops, but belt. All tags have been removed so I don’t know what kind of material this is.
