Not far out Ted, but not quite! We would wear a pullover for perhaps(not always though!) fishing,shooting, BBQ or going for a major walk or, some very informal setting and we rarely get the weather for shirt sleeves! In your sort of weather I don't think even the most hardened traditionalist would demand tweed and a tie!
