The Ultimate Dinner Jacket.
Alden has a view of simplicity but the original poster has described an outfit which is far off from Alden's view except for:
black vest vs. the OP's white pique vest
fold down collar vs. wing collar
pocket square OR boutonierre but not both vs. OP inquiring about wearing BOTH
I have never seen a black vest worn with a dinner jacket. I assume there is precedent for this. Are there pictures available? I am not sure if the illustation above shows such a black vest?
Regarding onyx studs, I recall that most of the pics of the English royal family at functions are with white studs, not black. So I don't know what the verdict is on this point.
Regarding Alden's recommendation for yellow gold cufflinks, I thought that white gold would be the formal and appropriate choice?
Whatever happened to the cumberbund with dinner jackets?
Does anyone have an illustration of the right Winter overcoat for a DJ?
Ex patent pumps, I gather that the concensus is plain toe patent oxfords is the right choice to wear with the ultimate dinner jacket.
Is the most formal dinner jacket made with shawl collar as in Niven's picture above or SB peak lapels?
