This sweater is really nice. It's perfect for cool days/nights and it's made really well. You could also wear a blazer or other type of jacket over this sweater with no problem. I wear a 42R in a jacket and a size 15 collar in dress shirts with 34/35 sleeves so I purchased a Large and it is pretty form-fitting. The pockets aren't very deep so I'd suggest not putting anything in them. My wife said I looked like a "sexy Mr. Rogers" so I guess this sweater is a win.
