That's what style is about to me, making your own look rather than aspiring to the runway. Anyone can do the latter and a huge factor for pulling something like that off is simplicity. I'm not talking tee and jeans simplicity but like your du in the napoleon, no crazy jeans and a plain white tee all worn (and worn in) with the other stuff in a way that really escalates the fit. More complex patterns/colors/fits require a mastery of that stuff in order to look better than what you just described though which most people lack. You also need a lot of stuff so that you can find stuff that interplays well with each other.
