A few years ago, Peter Frew came to New York with an important professional skill. He was one of maybe a few dozen people in the U.S. who could construct a true bespoke suit. Frew, who apprenticed with a Savile Row tailor, can — all by himself, and almost all by hand — create a pattern, cut fabric and expertly construct a suit that, for about $4,000, perfectly molds to its owner’s body. In a city filled with very rich people, he quickly had all the orders he could handle.

When I learned about Frew, I assumed he was some rich designer in an atelier on Madison Avenue. That’s what Frew hopes to be one day, but for now the 33-year-old Jamaican immigrant works out of his ground-floor apartment near Flatbush Avenue, in Brooklyn, and makes around $50,000 a year. His former living room consists of one large table piled with bolts of cloth and a form with a half-made suit. As Frew sewed a jacket, he explained how he customizes every aspect of its design — the width of the lapel, the number and size of the pockets — for each client. What makes a bespoke suit unique, he said, is that it’s the result of skills that only a trained hand can perform. Modern technology cannot create anything comparable.

As I watched Frew work, it became glaringly obvious why he is not rich. Like a 17th-century craftsman, he has no economy of scale. It takes Frew about 75 hours to make a suit — he averages about two per month — and he has no employees. A large part of his revenue is used to pay off his material expenses, and because his labor is so demanding, he relies on an outside salesman, who requires commissions. (Frew can’t even afford to make a suit for himself. When we met, he was wearing shorts and a T-shirt.) While he hopes to one day hire full-time assistant tailors and rent a Manhattan showroom, he knows it will be a huge challenge to get there.
