Vintage hand knitted lavender sweater

It is the prettiest color and knit. Light purple, lavender color. I had bought second hand from Sweden. Was told it was from the 80s, alpaca wool, light weight, but there are no tags. It does feel soft to touch and when I rub my arms on it but when I put it on, it's a little itchy to me. I'm very sensitive. Depending on how you'd like it to fit, I'd say this is a size L, please see pics. It's so pretty, I hope someone else gets to enjoy her! From a nonsmoking and no pet home. P2
