A friend of mine has been invited to a 'white tie' function. He intends to wear Highland dress and was discussing with me what would be correct. I don't know what is the strict protocol so if anybody out there does I'd be grateful and will pass it on. For what its worth I think strictly speaking he should wear a 'Montrose' jacket with a silk jabot. However this is not practical as it is almost impossible to hire them, and having one made is costly. A highland outfitter has advised him to wear a white tie and marcella waistcoat with his PC, but another has said that white ties and kilts are a not on. Hence the discussion.
