It's all about the colors. You can have multiple longwings as long as the colors aren't overlapping. I'm out of the game for Gramercy only because of my cigar shell Alden longwings (which I'm wearing today, but must admit the Gramercy are in Cognac calf are beautiful, and tempting). I also have burgundy shell MacNeils and chocolate brown suede Alden longwings - each of which has their place. If AE offers walnut shell MacNeils sometime in the future, I may jump on them.
