You probably need to find a more authoritive source. If others are wearing tuxes and gowns, then I'd wear the Prince Charlie (as opposed to a gown). Renting should be easy enough. They're not cheap to buy. But my understanding is that the Argyll is evening wear.

Argyll hose are the best choice for a formal event. Castellated tops w/ ribbon garters would be tops. Trying to find some to match your kilt may be difficult, though. You might be able to find someone who knits who could make them. Colored hose would be a good second choice. I like to wear hose that match one of the major colors in the kilt, and flashes that contrast strongly w/ the hose but match another color in the kilt. If you don't have the color you want in flashes, they're easy to make w/ some elastic and a bit of ribbon. If I'm wearing an Argyll jacket then I like to match my shirt w/ the flashes if I can. I like colors. I only wear a white shirt and white hose if I'm in the band uniform or playing for a funeral. I always wear a white tux shirt w/ the Prince Charlie.

I know that you can get buckles to tie onto your wingtips to make them look authentic. I have a pair of Sketchers w/ a strap and buckle that I sometimes wear w/ my kit as an updated version of the buckle shoe. I wouldn't necessarily recommend them for this though.

Check w/ rental shops and highland outfitters and look around on the internet or talk to anyone you can find w/ some authority. Maybe someone at Edinborough Castle would be able to give you some advice. They may have a web site. It's worth checking.
