At the end of the German occupation of Paris, Irène Karinska reopened her costume atelier and worked successfully until retirement in the 1970s. Due to the fact that Irène's work was often credited as "Costumes par Karinska", researchers have credited much of her work to her mother. Costume design of the 1953 French film adaptation of La Dame aux Camélias was credited to Barbara Karinska when, in fact, the costumes were designed by Rosine Delamere and executed by Irène Karinska.
