A high-priced denim boutique in Shockoe Slip? It seemed like a long shot. But Anthony Lupesco, the young chief executive of Shockoe Denim, believed Richmond was hungry for high-fashion jeans — and he was right. Business on South 15th Street has been brisk, he reports, especially for his custom-made denim, which is made to fit an individual’s body type. One beloved customer already has ordered six pairs from his personal pattern. Last month Lupesco launched online sales (shockoedenim.com), hot on the heels of a story in Southern Living’s May issue.
