Black Tie means a bow tie not a black coloured tie

[MacMillan of Rathdown]

I do not own, and refuse to buy, a full set of "black tie" garb. I would use such attire at most once every four or five years, and would have to manufacture reason to do that. I'm not likely to go to the trouble to rent formal wear, either--that level of formality is just too artificial for me. In short, if the invitation specifies "black tie," I won't be there. You need not worry about seeing me wearing a tartan tie over my tweed kilt at your precious black tie event.

To me this smacks of some sort of resentful, "inverse" snobbery which, quite frankly, I don't understand.

I don't care that you (and millions of other folk) ride bicycles on the public road (and often the public foot path) without paying one penny of road tax for the privilege, and without adequate insurance to cover third party damage-- that's what you do, so have at it, even if I am subsidizing, to some extent, your ability to pedal your bike pretty much wherever you want.

You, however, are not being asked to subsidize anyone who wears black tie, or hosts, or attends black tie events. Even, "precious" black tie events. As you have more-or-less admitted that you have no intentions of attending a black tie event, I fail to see what you have to be resentful or snobbish about.
