BB merino? Yes, I noticed the buttons just now, definitely twins!
I went with jeans due to the casual nature of my day today (studying in a library -.-). Had this been more business I would have went with a light brown cord or light grey flannel.
The outfit as a whole is dated, but I think it's the tie and trousers that are doing that. The coat is going to get a lot more wear than either of those.
