Activity for Ian

If I were wearing a tux, I'd probably go with a patent leather pump, but I'm planning on wearing a frock coat (see photo). Should I still go with the same shoe? Perhaps a calfskin boot?

Hi! I'm hoping any married person's or B2B can give some pointers. In our relationship, I (the groom) am actually the one doing more of the planning. She's got her opinions and obviously will be in charge of certain aspects, but I'm spearheading it...
