From what I've gleaned over the years, I think you're spot on. A turn-down collar shirt with studs is perfect for black tie. Solid-colour hose (anything but white) is perfectly acceptable, and probably even the best choice if you're trying to be conservatively within tradition. I don't think matching tartan hose are too much for black tie, but that's just me. If anything, I think tartan hose are perfect for black tie and diced hose are perfect for white tie.

Personally, I dislike black hose almost as much as white hose. Too extreme. I much prefer a middle-of-the-road approach with a colour that is neither too loud nor too boring.
