The Costanza Stratagem

The other day when I was getting a haircut, I saw a man out at the barbershop wearing a dark green L.L. Bean sweat suit, with a matching sweatshirt and sweat pants. Now, I'm the last person who should be criticizing other people's fashion choices, but this is a strategy I just can't fathom: "I'm willing to make an effort and spend some money to dress nice when I go out, but not at the cost of sacrificing my sweat pants."
