Derrick Adams’s “Style Variations” at Salon 94 features 10 large-scale portraits celebrating self-actualization and Black joy by examining themes of fashion and costuming. Inspired by the power of transformation found in the simple act of changing a hairstyle or a lipstick color, the monumental works draw from the salons and beauty shops found in Bed-Stuy, which he has observed and photographed during his 15 years living and working in the Brooklyn neighborhood.
