A few years ago, Charles Nolan quietly opened his shop in the basement of the venerable Luhrs Central Building across from Patriots Square downtown. He had a concept -- the hippest men's shop in town, and that was about it. Advertising budget? Hardly. Neon signs? Not in this lifetime. Word of mouth? You betcha. These days, Charles -- who doesn't even have a phone in his downtown haberdashery -- counts several Phoenix Suns as regular customers, and his clientele is growing by the month, eager to buy his primo Italian suits, his slick shirts, his excellent selection of ties. But Charles isn't just a clotheshorse. A major league jazz fan, he collects CDs, then sells them to his customers for a mere 10 bucks apiece. Finding this gem of a store isn't easy. But once you find Charles in Suite M, around the bend from Tony's Barber Shop, you're in for quite a sartorial treat.
