Thanks to the fellas who helped out with my inquiry about brown gunboats. Very helpful starting points - we'll see what I end up doing, will probably hold off on buying anything quite yet.
Another general question to the forum: what's the consensus on black shortwing/longwing bluchers. I've been indoctrinated to feel/believe that they are a bit of an oxymoron, as black should be reserved for the most formal of occasions (and thus most formal shoes). I wear a lot of browns/tans and have two pairs of shoes - black J&M Meltons to wear with a charcoal suit, and a pair of To Boot New York wholecuts to wear with black tie. I do not wear black tie or a charcoal suit terribly often, so they get little play.
On occasion I've considered black longwing (and/or shortwing) bluchers, but I feel like the "correct" answer is that there really aren't many occasions where they are a great choice.
What say you, gentlemen?
