The hand-cutters and tailors of Norton & Sons and other famous Savile Row outfits such as Gieves & Hawkes will continue to meet their needs in the intimate and discreet manner that keeps the Row close to their hearts and wallets.

British Fashion Council Chairman Harold Tillman said the creeping modernization in and around Savile Row that has seen Grant participate in Fashion Week and the footfall resulting from the arrival of U.S. clothing store Abercrombie & Fitch can only be a good thing for such a traditional brand.

"There isn't anyone in the world who doesn't know Savile Row and what it means," Tillman told Reuters. "You can smell the quality."

GQ's Johnston said that not everyone can afford the handmade bespoke suits fitted for the individual client, which start at 3,000 pounds and rise much higher for individual detail. But the purchase of one could bring life-long pleasure.

"Nothing makes you feel so good," he said. "It's like armor."
