NWOT Joan Vass cream long wool sweater

NWOT Joan Vass cream long wool sweater. Open in front; loose decorative sweater belt in back. About 21 1/4” across underarms. Length from shoulder to bottom is about 38”. The tag says it’s a size 3. I looked up a Joan Vass size guide which says that size 3 converts to a US size 16. Please check the underarm measurements I’ve given you to be sure it will fit.
