Wedding Recommendation

[KennethSime]

First off, congrats to your best friend's wedding!

On a related note, with an outdoor fall wedding in Tennessee the temperatures for the event may be 40 degrees F or 80 or anywhere in between. What are the options for a warm outer layer with formal Highland dress? It obviously wouldn't be worn during the ceremony, but if we end up in a cold spell I'd rather not freeze all day before and after. Good Inverness capes are incredibly expensive; would a traditionally styled cloak be appropriate?

I can't help much with the questions about fly plaids, but perhaps I can offer some thoughts about this section.

I should think that even at 40°, a jacket + waistcoat should be warm enough as long as you're moving around. A Montrose of Kenmore Doublet should be even warmer, as they're not open-front. A sweater is easy to throw on under your Argyll jacket, but I'm not sure this would work with a P.C. Perhaps one might wear a merino wool base layer under your shirt?

For country wear, many folks are a fan of Barbour jackets with highlandwear, but I don't think they qualify as formalwear.
