I'm trying to get a feel for how shoes are normally used. I understand cap toes are probably the most formal dress shoe (save for patent leather pumps, of course), and look good with any fine suit. How about monk straps? I assume they are best employed with wool trousers and a nice shirt and perhaps even a blazer, for a casual elegant look. Is that right? Also, what about brouges and semi-brouges? How, where and when? My take is that brouges and semi-brouges are fine with suits, but with more conservative suits -- say your standard issue 2-button pinstipe. Again, am I right on that? Any expert opinions would be appreciated.
