The cheerleaders train for hours to have a few minutes of spectacular performance, all at considerable cost to themselves and other women. Mr. Body Art is a model of self-fashioning, but only for a few hours in a convention center that tomorrow will be hosting Rotarians while he becomes just another guy on the street. Fashion alternates between conformity and unique self-assertion, and each depends on the other. Most of us spend our time between these two extremes, but we shouldn’t feel too smug about that. Among human beings, there are only differences of degree, never of kind.
