"Rules" for dressing up

[Chef]

thescot you are right on the mark.

Where black tie gets stretched these days is of course weddings. Unlike formal affairs of the past, weddings are often timed for the venues they are using. It is not unusual for a couple to get married at 2 PM and not start the reception until 5. Strictly speaking if they want guests in formal attire the men should wear morning coats to the ceremony and black tie to the reception however that is rarely, if ever, done. Black tie is considered acceptable for both the ceremony and reception in such situations. What is not acceptable is black tie dinner jackets when the ceremony is at 11 AM and the reception finishes by 6 PM.

So, a PC or Doublet would be an evening jacket and a grey Argyle would be a morning jacket?

And I would assume that you could wear the same kilt throughout—why not? If you can wear a kilt to a white tie event, and later wear the same kilt with a t-shirt while taking out the garbage, I don't see why you couldn't use it for everything in between. That's my opinion, anyway.
