VINTAGE MADEMOISELLE KNITWEAR SHORT SLEEVE SCALLOPED COLLAR WEATER

This cute piece is from around the 70s. Scalloped collar detail. Ribbed knit. There is one little snags but doesn’t look like there are any major stains. Irene style/100% acrylic. There is not a size tag. I tried on the shirt and I would say it’s a smaller medium. PTP 20”.
