I like the Evolver better personally. Whenever somebody says something is "out", it reminds me of the time a Nordstrom employee told me burgundy shoes were "out" and that is why they did not carry them.
Between the 3, I would have to say that Flatiron in Walnut calf. Walnut wears well with jeans and a grey suit (in my opinion).
However, were I to buy only one pair of AE shoes, it would without question be a strand in walnut calf.
Honestly dude, I think you should go for neither. Kent Wang will make you a MTM Tuxedo with all the trimmings (pick-stitching, full canvass, etc.) in Zegna caliber fabrics for around $900 USD.
You can pick your fabric and have every detail you might want made to your measurements.
He also sells a matching bow tie and cummerbund should you wish it.
When everyone was going on and on about the MA-1's in this thread, I could never figure out what the big deal was. They weren't that awesome....now I am about to order one in black lamb....am I a sellout?
