I think the sweater looks great. It would be very nice if the leathers could be brown to coordinate with the sweater and have the nightstalker as a contrast but I'd wear it. I might would go with a black kilt hose to tie the Black/Brown on the upper body to the Black/Brown on the lower body. Going with another color sock and you run the risk of someone thinking the socks were an after thought.

And you better watch out or that moose that dropped that antler might come back for it.
