I love this thread. I am totally guilty of trying to get everything defined too perfectly (only to rebel against my own rules) and am working to relax this tendency.
My only addition ... My dad's mantra that he drummed into us, from Shakespeare: " to thine own self be true" - if we live by this we're sure to have a consistency far deeper than colour palettes or pants styles - and I think this what comes through in your outfits, Jaime!
