I woke up this morning to a private message regarding what shoes to wear with a Highland outfit, now the outfit in question is a black tie outfit using a black argyll jacket with silver buttons. The gent asked if he should be using opera shoes. My answer is you should not. Here are a couple of photos of the shoes I would recommend for a Black Tie outfit.
Ghillie Brogues

The other shoe I would recommend is a wingtip or brogue shoe. Mine are from Florsheim and have served me well for years.
