formal evening dress: vest or no?

[Bugbear]

Please don't, Ted! I, for one, value your insight.

Thanks. It is a little difficult to deal with having learned that the jabot can be worn with any of the formal highland jackets, including the formal dress Argyle, then suddenly several people are saying it is for white tie and only to be worn with the doublets other than the PC.

When MacMillan of Rathdown has told me, directly, that the jabot can be properly worn with either a dress Argyle or a PC, along with the high throat waistcoat, or even an Eton jacket, I end up feeling that I am being singled out for his information, rather than the arguement being taken to him. He has been discussing this, here on the forum, for years now. I know very little about Highland attire, beyond what has been discussed on the forum.
