Basically, I do not wear (or own) any shoe that is not "canonically classical." The wildest I get might be an austerity brogue. But that has a good pedigree. I won't wear wholecuts, floating medallions, punched monks, diamond caps, or anything else. Basically the EG calalogue minus their "contemporary" models. What I will do is pair an unexpected shoe with a suit. I think it's an American thing to wear brown or burg where the English would expect black and also to wear larger-scaled shoes with suits. It's also a Naples thing and, I have noticed, something the duke of Windsor (not my sartorial idol, FWIW) liked to do. I never go the other way and wear oxfords with a blazer, however. Burg shoes should be shell, IMO.
