Vintage 70’s Levi’s Women’s Gingham Button Down Shirt Blouse Size M

Vintage 70’s Levi’s Women’s Gingham Button Down Shirt Blouse Size M Cotton lightweight paper thin burn it cotton blue & white gingham print. Had a single bust pocket with Levi’s tab. Vintage tag on color but does not include sizing tag. I wear large and can put on but it is snug leading me to believe it is a Medium. Pit to pit is 20 inches and length from shoulder to bottom him is 25 inches. No rips or wear but some discoloring that I have included in pics. Honestly it shows more in pics than in person. Button all attached. Smoke free home.
