I have a black shawl collared dinner jacket that I want to wear to a wedding that specified "Evening Dress." Tonight I met with several people going to the wedding (including some that are in it) and we discussed what we were going to wear. The answer all around was pretty much, "Suit." I don't want to be the only person in a tux that is not in the wedding party, but I really want to wear my jacket so I had a thought that I might dress it down with grey trousers instead of satin piped black ones. Could this work? Has anyone seen it done? Thoughts?
