CHANEL Knit Sweater with collar

CHANEL-Creations Paris- knit sweater. Fabric contents are 90% rayonne and 10% nylon. Creations Paris was created during the 70’s/80’s so that is my best bet on this piece. Very good condition but does need some love. Some stitching has come undone around collar although doesn’t affect when wearing it and possibly some slight staining around collar. No size but would fit an xsmall/small best.
