What’s funny about that is that technically, gentlemen shouldn’t be wearing tuxedos.
A formal ball is a white tie event. Gentlemen with colors wear scarlet (if that is what is customary for your hunt club), and gentlemen without colors wear tails (black tailcoat) and a white tie.
In white tie event, (such as a formal ball), servicemembers have a specific uniform, hunt club members with colors wear their scarlet tailcoat, and gentlemen wear tails, white tie, etc.
No, I am not Emily Post. But I did stay at a Holiday Inn Express last night.
(seriously, this stuff was beaten into my head as a child - I even know what a Black and White Ball is. Then I grew up and my family was horrified to discover I prefer to wear Carhartts and dairy boots. I think an aunt or two got a case of the vapors…)
So wanabe, if you would like to dress for the hunt ball, but scarlet is not appropriate for you, consider dressing as a gentleman should for a white tie event. I bet you would look quite handsome.
eta: I’m assuming that your hunt ball is truly a formal event, and not semi-formal or black tie. For a black tie event a tuxedo would be appropriate, though it is better to be overdressed than underdressed. Oh my God I sound like my mother…
