Vintage Lightweight Sheer Open Shawl Cardigan

All tags missing. Believe this sheer Cardigan is about a medium. Can wear it open or closed with one small eyelet hook in front. Measurements seam to seam when closed: Bust- 17" Acros Bottom- 18" Arm Opening (Top to Pit)- 8" At end of sleeve- 6" Length- 33.5" This shawl in good condition. Only flaw I see is one small snag bottom front. Please see last picture.
