Sketches by American designer Muriel King

Muriel King (1900-1977) was an illustrator and fashion designer based in New York City. Although mostly forgotten today, she was one of the first American fashion designers to achieve name recognition and was sought out in the 1930s and 1940s by the women of Hollywood and high society. She began her career as an illustrator for fashion magazines and department stores, and her skill as an artist was what enabled her to open her own couture salon despite having no formal training in cutting, draping, or sewing. Instead, her structurally detailed watercolor sketches were what informed her tailors and sewing staff of her intent. Her dresses were especially popular among socialites who appreciated the sophisticated and sensible construction of her designs. She began designing for Hollywood films in 1935, and the international reach of these films would in turn bolster the attention paid to American fashion design.
