PASTEL STRIPED cowl neck sweater 1970's 70's XS S

True vintage from the 1970's, comes to me from the original owner! Pastel/ivory striped cowl neck turtleneck top. Lightweight acrylic knit (washable). Drawstring bottom hem. Tagged as a S, runs more like XS by modern standards. 16.5" PTP before stretch, 22.5" long from the shoulder. Overall excellent condition, the last picture shows a little spot of yellow on the side. I don't think it's a stain, it's the exact yellow of the sweater stripes, so it might be a manufacturer flaw? Totally not noticeable in normal wearing anyway. (C11)
