Gustave Tassell was born in 1926, in Philadelphia, Pennsylvania, USA. He studied painting at the Philadelphia Academy of Fine Arts.
Moving to New York, he worked in the advertising and display department for Hattie Carnegie, who was well known in the fashion design world for both custom-made and ready-to-wear clothes. Seeing the design work of Norman Norell inspired Tassell’s decision to create clothes for women.
In the early 1950s Tassell moved to Europe where he did fashion sketches for Geneviéve Fath and became acquainted with American designer James Galanos. It was through the encouragement of Galanos that Tassell eventually began his own business in 1956 in California, though the designs Tassell produced were closer in concept to those of Norell than Galanos.
Tassell's design sensibility changed little from the 20 to the 21st century—he sought to create forward-looking fashion appropriate for elegant, confident women. He envisioned designs in natural fibers able to serve many purposes, with changing silhouette according to how the garment was buttoned, seamed, or tucked. Tassell aimed to produce affordable clothing with a sense of proportion, grace, and design. White gloves and pearls were the accessories one needs to wear with the refined, graceful designs of American Gustave Tassell. He designed for women who had a built-in serenity and who were not out to shock. His designs went beyond fringe and ruffle and were noted for their sense of proportion, simplicity of line, and refined detail. Through the use of seams, tucks, and gathers, Tassell was able to create sculptural forms which skimmed over the body, rather than a tight fit. The look was graceful and feminine. Skirts could be bell shaped, or gathered gently. The seams of a princess-style dress curved to suggest the bust and waistline. He designed clothes for both evening and daytime wear—separates, dresses, and coats. He designed versions of the black dinner dress, the shirtwaist, culottes, and the reefer coat. His interpretation was always graceful and feminine.
