The ideal time for the black argyll

[Nathan]

I'd love to know your opinions on when the black barathea Argyll jacket with metal buttons is the best possible option. I know it can serve many purposes if necessary, but that isn't my question. It will do the trick for black tie, but a Prince Charlie or doublet is ideal. You can wear it in the day, but a tweed is the preferred option for that.

I've read that is is a morning suit equivalent, so does that mean that it is ideal for one's own wedding pretty much? I have read sources like the old WM Anderson catalogue that stated a groom could wear full evening dress for a daytime wedding as the event will go into the night and he is the groom, but perhaps the proponents of the morning suit would disagree.

I have several options including few tweeds, the black Argyll with metal buttons, a charcoal worsted wool suiting fabric Argyll with black leather buttons, a PC, a Kenmore/Balmoral doublet and a single breasted velvet doublet similar to the GT doublet.

I also know Jock's advice about switchable buttons but my question is specifically about the metal buttons.

Aside from perhaps my own wedding, when should that be the jacket I reach for above all of my other options?
