Traditional Highland Wedding Attire?

[CMcG]

The photos and ideas are all much appreciated. Apart from everyone wanting to look their best, there appear to be a few common themes that I'd like to pick up on.

The first is dress codes for time of day. Before 6:00, we know it should strictly speaking be tweeds for daywear, or else formal morning dress (i.e., black barathea silver button Argyll or bbsba). In the evening, it could again be the versatile tweeds (as a suit equivalent) or else formal evening wear (i.e., black or white tie).

But there also seems to be a notion that the groom gets a special license to "take it up a notch," and so we have some people wearing what looks like formal evening wear before 6:00. I wonder if that pertains to the catalogue OC Richard posted that calls for "full dress" for the groom, and suggests "it is readily adaptable for evening wear afterward"? As in, the groom wears their absolute best, and it doesn't matter what time of day it is?

The second theme has to do with the rest of the wedding party. Some brides/families/in-laws want more of a say in people's attire... whether or not they get their way is another story. I imagine some negotiation might be required if there were to be any conflicting opinions. Any experience with that?

And it seems quite traditional that people are suggesting the groomsmen can pick their own attire, particularly that they can wear their own clan tartan. That also makes sense if people own their own clothing and won't be renting. There is something to be said, however, for some unity in the wedding party, without necessarily having to match. Did anyone come up with a strategy to tie their group together, without imposing a "uniform"?
