Yes, I'm to be installing officer for London Sovereign Chapter of Rose Croix. As such, the officer is normally white tie and tails or equivalent, although black tie would be acceptable. Other members of the team are to be black tie and tux or.... I know of at least one who will be kilted besides myself, since I moved the buckles and straps on his kilt a couple of weeks ago.

For myself, I'm thinking Sheriffmuir and vest, diced hose, and my "rodent" as you call it, but I'll wear my clerical shirt with its collar, which is after all, white.

The alternative would be horse-hair, but cantles don't fit well under my belly, so the rodent would be more comfortable.

Nice, very nice. I have a rodent, too. Mine's beaver, but on the very rare occasion I've attended white-tie in the last twenty years I've worn badger or seal. With beaver re-introduced to Scotland I would think it will become old-school sooner than muskrat, but that's years from now. Beavers don't often cross roads
