I too would add that a highly polished captoe shoe like the PA is an acceptable if not first-rate choice for black tie.
I would further give my assent to the statement that the OP is going to be very well turned out.
I seem to recall that James Bond did wear a cummerbund in some of the early Sean Connery films, but I could be mistaken.
Finally someone is making sense, OP you'll be well turned out in spite of a few things that aren't entirely conservative.
Enjoy the braces, but make certain you're getting formal braces and also make sure they're black or white, not colorful.
