I wanted to love this garment, but the fit is off. While very comfortable (feels more shirt jacket-like than most chore coats), the silhouette created by buttoning it up is not flattering. The shoulders are narrow with not much give, and the sides at the bottom flare out to create an “A” look. I’m 5’10” and 185 lbs and got a medium, for reference. My shoulders are a bit broad, but I’d still recommended sizing up - especially if you want to wear something thicker than a t-shirt underneath it. The chore coat looks fine unbuttoned, but the lack of versatility hurts it. It’s more like a fall mid-layer than true chore coat.
