Wouldn't be convinced unless you've heard otherwise. Their clash socks have always looked like this:
I actually didn't know that, but I still think they will, they have used the same socks with the basic design of the bulldog guernsey (minus the bulldog) on the socks since they changed to the "Western Bulldogs" moniker, and since they have neither that style, nor the bulldog on their guernsey anymore I think they will change back to their traditional socks too.
Obviously I could well be wrong, they did wear last year's socks with their traditional guernsey in round 13, I'd be interested to see what socks they wore with their hoops guernseys they've worn for heritage round if anyone can find a picture.
