Thank you for both the welcome and the advice here and in the other thread. I did spot that cardigan and do like it however I am leaning more towards a chunkier cable knit cardigan. I just really want one, and from all these suggestions am definitely leaning towards a navy/black one.
just saw these two on Barbour, they look pretty nice
Mens Barbour Clifton Chunky Shawl Lambswool Cardigan - Barbour By Mail Online Store
Mens Barbour Moss Shawl Shetland Wool Cardigan - Barbour By Mail Online Store
Although they don't have the latter in navy.
