In response to Tobus and MacLowlife; Just so it isn't misunderstood...

I was not intending to say that you all should dress plainly and unadorned, or that there is anything wrong with Highland evening attire.

I think it can be very attractive. I personally do not feel comfortable wearing all the silver buttons, chains, cantles and so on, so I have to keep separate in my mind, what I would feel comfortable wearing, and what might look good on other people.

It's just not my way. It's also not my way to get bent out of shape if some other guest is dressed in some other way than I. Were I the host... That is who should be concerned about what the other guests are wearing.
