Vintage McGregor Wool Cardigan Sweater Size XL/L Olive Green Kurt Cobain

Vintage 100% Virgin Wool McGregor Cardigan Sweater. Same style as Kurt Cobain wore. I bought this on eBay for $62 and sadly, it is a bit small for me. Though labeled as XL, I think it fits like a snug XL or a Large with some room. I'm 6'1" and 190lbs if that helps. I think the knit has probably just tightened a bit over time so it feels well constructed and solid, but just not quite roomy enough for me. Condition is very good for an old cardigan, with some small holes (see pics) typical of older pieces. Listed as 50s by eBay seller, but I'm not sure. I wish it fit! I've seen this style of vintage sweater listed for hundreds of dollars on eBay (probably because of the Cobain connection). Thanks for looking. :)
