Every now and again, a fellow _flosser texts me a question I just can't answer—either because I don't know the answer, or because of the medium's draconian character limit. The first one of these made international news. It's probably all downhill from here.

Today's text comes from Colin Perkins:

"Why does Steve Jobs always wear a black mock turtleneck? I can't think of another person as rich or powerful who's only ever seen in one outfit."

Anyone have a theory? Or facts, even.
