Vintage 80s M.J. Carroll Pullover Sweater Size Small

This is a beautiful 1980s vintage pullover heavyweight knit sweater that is bright blue, aqua and metallic gold with a striking red rose. This has a slight scoop neck, sleeveless, and ribbed hem, and overall in good condition (see photos). Tag is a medium but based on measurements will fit a size small (4-6) the best. Approximate measurements flat: Pit to pit: 18” Shoulder to hem: 23” Recently purchased for myself and so bummed it doesn’t fit!
