Fair Isle Linen, Wool & Cotton Sweater Vest

Despite the label & on line description, this vest might have a tiny bit of linen & cotton, but the majority is some sort of wool- alpaca? Merino? It’s a heavier weight and very soft. I bought it for myself because I wanted a fair isle design including purple- and this fit the bill. Size M is a bit large on me but I like a relaxed fit - and when worn over heavier pants- wool or corduroy- it works for me. I would think most women would size down from their normal fit.
