Vintage neutral collared stripe cardigan‎ size medium

Vintage style cardigan with a collar, button front and stripes. There are no tags so I’m unsure of the material and size. I’m recommending for a size medium. It’s modeled here on a size medium who is 5’1 and 130 lbs for reference. Boxy fit with great neutral colors and no noticeable flaws. Approx measurements: Shoulder to shoulder- 15.5 inches Pit to pit- 21 inches Length- 20.5 inches
