In her heyday she was described as "one of the big 10 of the British fashion world",[4] the others being Digby Morton, Norman Hartnell, Charles Creed, Molyneux, Worth, Mattli, Victor Stiebel, Hardy Amies, and Peter Russell.
[14] Earlier, she created a wedding dress for Peggy Bryan for the 1945 horror film Dead of Night—the slim-fitting bridal outfit made under the Bianca Mosca label was photographed by the Ministry of Information.
[16] In early 1949, a review of her collection in the Australian press highlighted "semi-eveningwear"—sleeveless, floor length gowns in organza or brocade with full underskirts and coats designed on similar principles.
[22] Mosca designed a showstopping black brocaded silk evening gown for Margot Fonteyn, worn by the prima ballerina at a reception in New York after her opening performance of Sleeping Beauty in 1949.
[24] By December 1949 Mosca's eponymous label was failing and the receivers were called in—this during a post-war slump in sales of British couture, due to a dwindling home market and overseas buyers' preference for Paris fashions.
[28] In 1954, the Council of the Royal Society of Arts took over the administration of the Bianca Mosca Memorial Trust, introducing two new bursaries for designers in the field of fashion, shoes, millinery or jewellery and announcing that the awards jury would include Edward Molyneux and Audrey Withers.
