He never set out to be the best-dressed drunk in town. Concerned with perception and looking just the right way when presenting himself in public, he took care to debut coveted, new wardrobe items in just the right way and time (even using the word “debut” when unveiling a new pair of shoes or a new coat). At least the sartorially concerned was one side of his personality.
The other, alcohol-soaked side, might throw these moderately expensive threads on, and run down to replenish the stock. Not at all caring what public perception might be.
