Patrick, nice to hear from you.  I swear by one of their Scottish-made wool cardigans.  I've had it about ten years and still - much darned though it is - it refuses to fall to pieces. 
My late father - a fisherman - was a UK Bean devotee.

This is how I discovered I don't need to fear "slightly fitted," at least not from LL Bean. I got the "port" color.

For sport shirts I am increasingly inclined to go with an open collar (ie. not a button-down collar). Unless there's a sweater involved. I will not have a collar flopping around outside a sweater. Makes me look like "Freddie," the dodgy weirdo who sponges off the murdered actress but is quickly cleared by Columbo.
