I'm helping a close friend get his first kilt in his clan tartan, Buchanan. He is a casual guy, like me, and I am going to gift him with a decent sporran and belt. I can't remember the tartan well enough to know how well brown will go with it, or should I get black instead. Again, he'll wear it casually and I prefer brown when doing the casual thing, so I'd like to get him brown but how well will brown work with the tartan.

Opinions?
