I, for one, am tired of the stereotype that geeks can't be expected to maintain a wardrobe of nice clothes, understand what goes with one's bodyshape, skin-tone and how to mix fits, patterns and colors etc.

I'm impressed. You just described my wardrobe quite accurately. Technically the shoes are "light hiking shoes", but you get the idea.

On a typical day I wear a nice pair of jeans, a white collared shirt, and a sweater.
