Following the end of W.W. II, British designers applied their newfound sense of freedom to the clothes they made. Monochrome fabrics in dreary colors were out; playful shapes with vibrant colors were in. One of the era’s preeminent pattern designers was Jacqueline Groag. Her textiles, fabrics, and wallpapers featured whimsical shapes—geometrics, flowers, figures—in brilliant colorways: pinks with reds and oranges; yellows with blues and reds. A new exhibition displays her work in various stages, from initial sketches to printed fabrics to dresses made from her cloth. —Jensen Davis
