A newly formed ballet company, the Ballet Russe de Monte Carlo, directed by Colonel de Basil and René Blum requested she make costumes for their first season.[1] The costumes were designed by Christian Bérard, André Derain, and Joan Miró, and the choreography was by George Balanchine and Leonide Massine, both choreographers with whom she had worked previously. Bérard, Derain, and Miró would provide a general sketch, an idea, but it would be Karinska who expounded upon the concept, modified it, chose the fabric, quality and quantity, and decided how the concept would be implemented. During Karinska's brief career in Paris she also collaborated with Balthus, Cassandre, Soudeikine, and Vertès, and other painters and designers.
