Beginning with Norma Talmadge in Poppy, Banton designed clothing for Pola Negri and Clara Bow in the 1920s.
In the 1930s and 1940s, Banton designed for Kay Francis, Lilyan Tashman, Sylvia Sidney, Gail Patrick, Helen Vinson, and Claudette Colbert.
Glamour, subtle elegance, and exquisite fabrics endeared Banton to Hollywood's celebrated beauties and made him one of the sought-after costume designers of his era.
As viewings of such films as The Gilded Lily (1935) and Desire (1936) reveal, his costume designs were marked by form-flattering cuts (often on the bias), rich fabrics (such as satin and lamé), and extravagant textures (beads, fur, and feathers).
Because of his worsening alcoholism, and according to some commentators, at the instigation of his assistant Edith Head, Banton was forced to leave Paramount.
