Vintage Artesanias Inka 100% Alpaca Fair Isle Patterned Red Knit Sweater Size M

Very special find! Beautiful knit sweater with lots of patterns in shades of red with black and orange. Zips up. Tag says: Artesanias Inka 100% Alpaca Baby Alpaca 100% Made in Peru VEERY soft. In excellent vintage condition with no snags or stains, maybe some light pilling. No size tag. To me it seems like a women's medium, will also suit a small which I know because that's my size. Approx. Measurements laid flat: Pit to pit: 18.25" Shoulder to arm hem: 18" (a little short on me but I am 5'10" so most sleeves are too short for me) Shoulder to bottom: 22"
