St. John by Maria Gray vintage color block sweater dress purple red and black

St John by Maria Gray vintage color block midi sweater dress purple red and black. There is no size tag, but measurements are in photos. I would guess this is a medium/large. This dress is in pretty good pre owned condition but has some signs of wear. If under the right light you can see an oil spot on the mid section of this dress as seen in pictures. Very stretchy fabric.
