Vintage Quark Sweater Southwestern Blanket Turquoise Aqua Blue Polo Long Sleeve

Vintage 80s(?) Quark Southwestern blanket print long sleeve polo style sweater with solid color blue ribbed collar, cuff, and waist and a three button placket. The buttons are some sort of plastic material, but are meant to look like the braided leather brown buttons. The southwestern blanket pattern is blue, turquoise and aqua. Laying flat measures 24 inches shoulder to hem and 19.5 inches armpit to armpit. to me, the style is unisex. I don’t know if this sweater is wool or acrylic, but it has been treated like wool and dry cleaned. There is no fabric content or size tag on this garment. No noted flaws. Based on the measurements and the unisex style I think this would fit a modern men’s small or women’s medium best but please double check measurements to ensure the proper fit for you
