The tag says JC Penney Misses Robe and it does button all the way up the front.
It has a very 70s feel to me but has a tag that could in my opinion have come from anywhere during the late 70s to 90s.

1 small stain in the back in between shoulders. smaller than a pencil eraser. neckline has little embroidered flowers.

Tagged a size medium and true to size.
