First Ave. I'm an idiot.
I love my black Park Aves and I wear them often. The Fifth Ave isn't much different so if you don't care for the Park Ave I'm not sure you'll really care for the Fifth Ave either.
If I were in that situation, it would be a McAllister. I've become enamored with wingtips and don't like bluchers. However, I would advise everyone else to get the Park Ave unless they had a better black captoe already. If not the Park Ave, then the Carlyle. Fifth Ave in black seems like a cop-out.
As I said the other day here, I think the FA is a very versatile black shoe. While I wasn't over the moon about them originally and only purchased them because I got mine dirt cheap, I love them now, and I'm glad I got them instead of the PA as my only black pair. I don't think it's a copout, because I'm not going to a funeral in a full brogue. Just my two cents.
The Carlyle in black would be utterly tied to a suit in my opinion (and aside from a navy blazer with charcoal trousers I tend to see the black PA the same way), where as the FA can be worn with more conservative business casual attire as well. Anything less than conservative business casual and you probably ought not be wearing a black shoe with it anyway.
I say get the FA in black with Dainite and you have the only black shoe you'll ever need. Any black shoe after this can be filling a want if something really strikes you.
I'll wear them... both days. *insert world ending here*
I'd say it depends on your relationship with your SA. I'd be willing to bet that mine would do this for me.
The Delray wouldn't be a bad choice either, but I would prefer the Jodox.
If you are wanting something with a little more personality, have you considered the Cornwallis or Flatiron? I wouldn't be ashamed to rock either of those as a guest to a wedding.
