Including the U.S. in its earliest days - here’s John Jay, first Chief Justice of the United States: John Jay - Wikipedia. I’ve seen this actual painting at the Supreme Court.
Formal is white tie, informal is black tie, and morning suits are worn between noon and dinner.
Business suits are blue or black.
Watches are not worn at social events.
Men don’t have a hell of a lot of rules to follow, so I don’t think this is too onerous.
If you’re wearing a kilt, is should be ceremonial, and therefore white tie and watch-less.
Black tie, white tie and morning dress are all formal. (And there are still other formal modes, e.g. court dress, but let’s not worry about those.)
And they are certainly formal in the sense that a kilt is formal. Kilts can be worn at white tie, black tie and morning dress events, and there are conventions in each case for what should be worn with the kilt. As regards ties, if wearing a kilt to a black tie event, you would generally wear a black tie, but at a white tie event you would wear a white jabot. At a morning dress event a grey tie would be strictly correct, though any solid colour or, if appropriate, regimental-type stripe is probably acceptable, such is the laxity of our age.
I paid 400 pounds for a second hand wig. Gown was about 490 Pounds if memory serves. Bands along with collar were another 50.
Chambers and sometimes Court offices had spare ones to wearvin
I am wearing the bands and gown as I type.
In an episode of Downtown Abbey, the Earl for some reason was unable to come to dinner in the expected white tie and tails, and wore a tux instead. His very traditional mother the Dowager Countess said disapprovingly, “You look as if you’re going to a barbecue!”
The way men’s business clothing is trending in the US, the business suit might one day go the way of the wig, surviving only as a relic worn formally in the courtroom.
There’s a fairly regular cycle in which one style of formal is superseded by something which at the time is considered informal, but becomes the new formal. The full frock-coat was succeeded by the tail coat, which was considered casual because it was cut for riding on a horse, rather than in a carriage. (The transition from knee-britches and host to trousers occurred at about the same time, and for the same reasons.) The tail-coat in turn was succeeded by the dinner jacket, which had no tails at all so it was convenient for sitting down in. The dinner jacket was succeeded by the lounge suit, which we now call the business suit - a telling change. The business suit is in the course of being succeeded by “office casual”. And so it goes.
