It was a particular kind of modern dress shirt, a reproduction of a dress shirt that would have been popular in the sixties but had been modified to appeal to people who could not remember the sixties. Therein lay the problem, because Ed Borger would remember the sixties, he would remember being a teenager in the sixties, and he would avoid such a shirt because it would not seem retro to him, it would just remind him of a time before he had really gained social confidence. So someone else must have bought this shirt for him, a person who could not remember the sixties.
