I was always told that the unbuttoned bottom button was brought about by King Edward VII's lunch. (Reigned 1901-1910)

When wearing waistcoated suits I have generally observed this bottom button custom but having also worn Mess Kit in a previous life... If you turned up there with your buttons undone you'd be on duty indefinately so I know it's not a hard and fast rule that you MUST leave it undone and it seems quite acceptable to do what ever you like...

Jock? I believe you have far greater experience in these matters than I therefore in future, when I'm in proper highland attire, ( "If only" I hear you cry!) I think I'll follow your lead on this. I'll leave the unbuttonedness for my Saxon suited days.
