Vintage 80's, Super BIG,Oversized, LONG Green & White Striped Sweater

This cute sweater was one of my faves back in the 80's & 90's when big, oversized tops were the rage! I can't find a fabric content or size tag, but it feels like a cotton/ramie blend & please see my photo measurements for size. I would say it will fit size L/XL. It has long 3/4 sleeves with 10 tiny metal buttons which can be worn partially open, if desired. Still in very good condition! Smoke & pet hair free home.
