Barkley L. Hendricks has his own distinct sense of dress. On a recent mucky day, the artist is in a gloomy monochromatic ensemble: black loafers, black jeans, black vest over a black oxford, and a black handkerchief wrapped around his neck, accentuating his fuzzy salt-and-pepper goatee. His accessories have a little more quirk: a leather fedora, a trio of chunky gold chain bracelets and a toothpick tucked discreetly behind his ear.
