I have a (non-formal) brown sporran with a pewter (gray-silver) accent on it. I wear it with a brown kilt belt with a brass/bronze buckle. It BUGS me.....it shouldn't bug me so much, but it does. One of these days I'm going to get under the leather flap that holds it on, cut it off, get it bronze plated (costs a few bucks, not much) and sew it back on.
