Vintage Argyle Pattern Crewneck Sweater

Butter yellow vintage sweater with a thick ribbed crewneck and ribbed hems. No notable flaws. No inside tags except one small one with numbers on it. Because of the measurements, I believe it is a size small or medium, but please see them to ensure fit! Feels like 100% wool, it is a bit scratchy so I would recommend wearing a long sleeve underneath it. approximate measurements pit to pit 19.5" length 22"
