What to wear to a friend's wedding?

[Wareyin]

I have 2 weddings coming up, and I am planning to go kilted to both. This will be my first time publicly kilted, so I'm excited, but would like to get things right. I currently own an 8 yard Mackenzie Modern, even though I have no relationship that I am aware of. I just liked the tartan. I can't get either friend to nail down how formal their weddings will be, but one is being held at a fancy ballroom. Right now, I have a black day sporran, and lovat green hose. I plan on buying one jacket to go to both weddings, but am undecided on Prince Charlie, or Argyll. My wife loves the look of a PC, but I'm concerned about being over dressed, as I think the kilt will stand out on it's own. I also expect to have to buy a formal sporran.

So, I am asking for advice or opinions on Jacket, whether I should buy a "universal" tartan such as Black Watch, whether lovat green hose would go with Mackenzie at a wedding, and anything else, Please!


edited to add: I would love to buy my clan tartan, Watson, but that is not in the finances right now. I'm looking at the dreaded Pakistani jackets off eBay, as well as kilts from UtKilts.com
