Preowned but in excellent condition. Estimated to be from the 60s. No piques or holes. Minor staining under white stripe near arm pit. Could use a cleaning. Some pilling in spots but is normal for these type sweaters. Please see pictures for condition and measurements. This shirt does not have a tag to tell the maker, size, or material. Based off of the measurements below, i'd put it into a medium.
