The Tweed Argyll.

[MacMillan of Rathdown]

So, were I invited to an event stipulating Morning Dress I would wear a charcoal grey Argyll, it being the closest in appearance, as I would want to be kilted but at the same time avoid contrasting too much with the men in Saxon dress. Were it an outdoor function where the men would be in check tweed I would wear a kilt jacket of similar fabric. Apparently this entire line of thinking is non-Highland, if I understand Jock Scot correctly.

Richard, it's all down to what it says on the invitation. If the invitation specifies morning dress, then that's what would be worn: black morning coat, tan or grey waistcoat, grey striped trousers; if kilted then a black Argyll jacket with black waistcoat would be appropriate. In both instances the coats should be of superfine wool or barathea; tweeds-- of any shade-- would not be worn. If the invitation specified, or included, the wearing of a lounge suit, then it would be permissible, if kilted, to wear a charcoal, or other coloured, tweed or wool "day wear" jacket. In the summer, especially at weddings (and the enclosure at Royal Ascot), morning coats are usually a pale, pearl grey colour, rather than black.

As far as "men in Saxon dress" goes, aren't they wearing spiked helmets and carrying Mauser rifles? Oh wait. That'd be the men in Prussian dress, wouldn't it?

(I see Jock got in a few minutes ahead of me-- serves me right for answering the telephone!)
