I would disagree with not being able to wear a waistcoat without a jacket, though I might say a tuxedo waistcoat might seem a tad bit odd. Living in South Georgia where the humidity often keeps the temps pretty high, I have frequently donned a waistcoat with tie and sans jacket for dressier occasions. This I think will come down to the style of the waistcoat though, and I would go with my gut: if you think it looks good- wear it, if you feel awkward in it- dont.

Given the relaxed attitude to formal dress in your part of the country and the casual ceremony, I would suggest this option for above the waist (and keep in mind I'm from the fashionabley conservative South): a white button down dress shirt with no tie and wear a less formal waistcoat unbuttoned. If you want to wear a tie I would keep the waistcoat buttoned. I'll try and put up some pics later today to demonstrate... I must add that I would prefer to err on the side of being over dressed; folk will rarely fault you for looking your best!

Regarding ties I prefer a solid colour to match one of the accent colours in my tartan, but a tie in the same tartan would work well with a waistcoat (buttoned), and I think most club ties do well with a kilted kit. I've seen my chief and his family wear some very bold ties with their kilt, but they have that very distinctive British fashion sense that I'm still trying to come to terms with...

Dont forget to post some pics from the wedding and reception etc (especially if there's lots of hot chicks in them!!!)...

I personally would ditch the banded tux shirt, and got with a lay down collar and a tie. But, that's simply my opinion.

I have a wedding to attend in a couple of weeks. It will be an afternoon, outdoor wedding. I plan to wear my lovat grey, argyle jacket with a white dress shirt and black tie, Henderson (ancient) kilt, grey hose with black flashes and a pair of Doc Marten, black, wing-tip oxfords. Oh, and a plain black, three tassel, day-wear sporran with black 2.5" belt. Being a guest, and not wedding party, I wanted to avoid blending in with them... ie. black jacket.
