This must be hard times for independent retailers of high-end fashion, particularly when clothes can be marked down for next to nothing at chain stores such as the Gap, knockoffs make function secondary to form and folks just don't have the bucks to shell out for designer labels. How Harry DeMarco (H.D. himself) weathers the economic storm is a testament to his good design sense, entrepreneurial instincts and indomitable personality, which makes shopping at H.D.'s feel more like schmoozing with a close friend. No uptown suits are sold here, just cutting-edge shirts, sweaters, shoes, pants and jeans. For decades, Harry and his true love, Vicky, who runs the nearly adjacent H.D.'s for women, have built up a devoted customer base and brought Europe back to Dallas for the hip and hip hopefuls. And they have done it with the kind of high style that will charm the pants right off you. Or right on you.
