The Disguise

"As he was at present dressed in a seafaring slop suit, in which he looked as if he had some parrots and cigars to dispose of, I next discussed with him what dress he should wear. He cherished an extraordinary belief in the virtues of "shorts" as a disguise, and had in his own mind sketched a dress for himself that would have made him something between a dean and a dentist. It was with considerable difficulty that I won him over to the assumption of a dress more like a prosperous farmer's; and we arranged that he should cut his hair close, and wear a little powder."

Charles Dickens, Great Expectations. 1861. Dover Thift Editions, p 261

This makes me want to do research...
