Nobody can doubt your experience M.O.R. But as has been pointed out, ANY national dress option is going to make you look different to those dressed in white tie and tails. It may actually serve to open conversations where you may then demonstrate your wit, charm, and intellect.

However I don't think this is the point of this particular thread - it is to do with graduation - a white tie (as at St Andrews) doesn't come with the full list of other do's and don'ts. Nobody will be wearing a graduation gown with/without mortar board and the hood of their degree at a diplomatic ball.
