Just a thought... How about a white sporran belt?

The only sporran I would think would work would be a horsehair sporran which is of course a military sporran, otherwise I just do not see it working.

I've never seen a white kilt belt, but Penny's of Thunder Bay sells a white military sporran and strap. See it here: http://pennys.ca/purses.php

I don't think it would look good, but it might also go with one of those Saltire sporrans (which I don't care for in the first place).
