Ron,I think we have one of these trans-Atlantic mis-understandings here. In UK terms the term "dress" in male attire means formal attire. A suit(business or lounge) in UK terms is NOT dress wear.I guess, for us, dress(formal) wear would be, for daywear, the morning suit, or, in kilt terms a black barathea, silver buttoned, Argyll. I am not sure if you should wear your dress tartan with that outfit,but I never have.I don't think you should as we are talking formal day wear here. Oh, these d--n dress codes!

The formal evening(dress) wear in the UK starts with a dinner suit(tux) and black bow tie, or, again in kilt terms a Prince Charlie jacket and(in times not so long gone) a kilt made of your "dress" tartan. These "dress" tartans were often lighter in weight and made of "super standard" cloth.

Of course not all clans have a day(hunting)tartan and a "dress" tartan and certainly these days not many people have the two.

I have had more than a sneaking suspicion that you chaps over there, have regarded the term "dress" in quite another way,am I right?
