Or the pirate's code? Although I do think it's possible to dress objectively well and objectively badly within the context of this thing of ours, I'm often reminded of a line from Hamlet. "There are more things in heaven and earth, Horatio, than are dreamt of in your philosophy." It's entirely possible for something to look good and be outside of the "rules." Heck, you could wear a bunch of, like, Rick Owens or something, and not look bad. I think has a point -- the more you know about clothes, the more effectively you can dress.
