That's interesting. I was under the impression that black tie was meant to be a less formal set-up, in comparison with white-tie, and hence, wing collars were generally shunned when people moved away from white tie to black. But you might well be right on the historical evolution. It's certainly more commonly seen at white-tie events these days, even amongst those who do bother, than at black-tie ceremonies, I believe.
Did you get grosgrain or silk on your DB? I'm still undecided on what's the proper form -- if there's one -- for a DB with a shawl. From the first picture, it seems like it's satin/silk.
