Thank you all so far. It's good to see I'm mostly on the right track.

A few items that were mentioned:

Diced/Argyll/Tartan hose- I do plan to have a set of either Argyll or tartan hose made, but I'm waiting until I finish my tartan design and get it made into a kilt. They're just too expensive to be made for a kilt that I'm already almost too small for. (I'm on the last hole on both left and right straps).

Red hose- I just don't think it's quite within my comfort zone yet. The last time I wore red hose they had a shin guard in them for soccer I do have bottle green, but I fear they would read just as dark as the navy, so it may be 6-of-1...

Sgian Dubh- no, I'm not wearing one, even though it would be perfectly appropriate for the event. I have one being crafted by our own Drac right now in a trade. I've never been swayed to buy a commonly available one. They tend to be too artificial for me with either plastic handles or blades that won't take an edge, or just too garish. I should have it ready for the Burn's Dinner in January

Kilt Pin placement- I'm still waffling a bit on placement, it may go a touch lower, but I generally like it a bit higher than seen on many.

The hunt for my linen pocket squares continues

To answer a few specific comments:
BLHS209- I'll probably be selling this one after St. Andrews Day, if you're interested. I made it specifically for this event.

McMathTX- I actually picked up the waistcoat on eBay HERE. They don't seem to have the waistcoats separately right now, but do have VERY nicely priced PC/WC sets.

beloitpiper- We'll definitely see you there

thescot- I made the mistake, LONG ago, of polishing a pair of boots before they were broken in, and it was a colossal waste of effort. Ever since that time, I've ALWAYS broken things in first. I did go back and forth on the waistplate, even picked one up. After trying both looks I really liked the waistcoat better. I think it has to do with the starkness of the black/white contrast against the tartan and where the kilt lies on the waist. The waistcoat hides that line while the waistplate seems to make it the focus of the outfit. I'm still getting used to formal Higland dressing, and it's a LOT less slimming than my standard tux (shawl collar, one button jacket with cummerbund.) A lot of it is probably just comfort level.

This forum is such a fantastic wealth of knowledge and ideas.
Thanks to all who have commented and critiqued so far.
