Here's a question (that I could begin an entire thread on, but I won't): what are some ideas for a formal overcoat? Black is a natural choice, but I found something in navy cashmere with a fox fur collar. I know it's over the top, but could I mix black tie and a dark navy?? I don't think so, but I'd like confirmation
Nice! I would say no, unless your tux is midnight blue, in which case, maybe. A little over the top, maybe, but in a tasteful way if accessories are similarly bold.
