Rare Plus Size Large Vintage Paisley Print Dress from 1970s-80s

This plus sized vintage 1970s paisley print dress is in great condition! Groovy wooden buttons. Not lined (so needs a slip worn underneath probably). No label but I think this is made of acetate - polyester because the fabric is a little stiff and slightly shiny. I noticed what I think is a white tape mark that's barely noticeable. I think that this is a size 18, but pay attention to the measurements below to make sure that they fit you: 40 inches long 42 inch bust 36 inch waist 42 inch hips
