Vintage Kimlon sweater 60s/70s

I bought this at a vintage shop in Los Angeles last year and have never worn it. The tag is still on. I paid $65. Not sure exactly when it’s from. I’m pretty sure it was listed as 1960s. Looking up the brand, I think it’s 60s or 70s. The brand is “Kimlon, 100% virgin acrylic fiber, hand washable, made in the Republic of Korea.” The size on the label is a Large, but it fits XS/Small. It does have a small spot on the front. I circled it in the last 2 photos so you could see it. It’s possible that the spot could come out with dry cleaning, but I’m not sure.
