Vintage Napa Valley Petites Abstract Sweater Size P

Super cute vintage cardigan from Napa Valley Petites in a size P. Not 100% what that means-but armpit to armpit is about 17 inches and shoulder to hem is about 21.5 inches. 15 inches from armpit to sleeve hem. Super fun detail with beads, velvet ribbon and embroidery. Great vintage condition, no flaws. Comes from a smoke and pet free home. Thanks!
