In his use of novelistic techniques in his nonfiction, Mr. Wolfe, beginning in the 1960s, helped create the enormously influential hybrid known as the New Journalism.

But as an unabashed contrarian, he was almost as well known for his attire as his satire. He was instantly recognizable as he strolled down Madison Avenue — a tall, slender, blue-eyed, still-boyish-looking man in his spotless three-piece vanilla bespoke suit, pinstriped silk shirt with a starched white high collar, bright handkerchief peeking from his breast pocket, watch on a fob, faux spats and white shoes. Once asked to describe his get-up, Mr. Wolfe replied brightly, “Neo-pretentious.”

It was a typically wry response from a writer who found delight in lacerating the pretentiousness of others. He had a pitiless eye and a penchant for spotting trends and then giving them names, some of which — like “Radical Chic” and “the Me Decade” — became American idioms.
