Vintage Bonnie Boerer Embellished Sweater Size Medium black

Vintage incredible top! I am selling this for a friend, and it does not have a fabric contact tag nor a size tag. From measurements I am estimating this to be a size medium. Please review measurement photos to verify what you need. Fragrance and smoke free. 3/4 sleeves Fabric to me feels like an acrylic blend. No guarantee on fabric content! Zz
