Thanks for the reassurance, everyone! The sweater is a hit. I wore it last night to go have dinner with my husband at a new-to-us place, and it wound up being the perfect choice because we got seated in a closed-in outdoor patio on a brisk night. It was perfectly pleasant wearing a cotton sweater. Hubs likes it too (always a good thing!).
I have now successfully updated my F/W knitwear. The collection was looking tired when I pulled it out at the end of the summer, as I think every sweater I owned was at least three years old, some as old as 15+ years! The exception was the nice basic solid-color V-necks I found last year from Boden and Rag & Bone. So I was in the market for a couple of new *interesting* and modern sweaters, and this is just the thing I needed.
