A few months back, Michelle came home with a pair of pants she’d bought at Goodwill. “They were camo and seemed sturdy,” she said. “I wasn’t sure they were your size, but they weren’t that expensive.” She said all this anxiously, as if she might have done something wrong. She handed me a pair of digital camo pants, inside which a tag read, “Trousers, Army Combat Uniform 50%/50% Nylon Cotton Ripstop Blend, Wind Resistant Poplin.” They were “Medium-Regular” size, according to another tag, accommodating waists from 31 inches to 35 inches, and inseams from 29½ inches to 32½ inches. Who but the Army could make one pair of pants with 4 inches of waist adjustment and 3 inches of inseam adjustment?
