Depends on how the version fits you. I had the version a while back in the same size as my codex and it fit- but IIRC it was 1-1.5 inches longer than the codex and the sleeves and shoulders were tighter.
I currently have a clay Stark in M from last year. I now have no idea what to do with new sizing for any of the other sweaters... If I wanted another Stark, do I just size up one to L?
What about the other sweaters like a Fang? or a Limbo or lighter sweater?
This is apparently what has happened w/ Stark sizing at least. Not sure on others.
