Fedorovitch designed for several British choreographers including Ninette de Valois and Antony Tudor, as well as for opera and theatre.
[2] In her 2012 article in Research in Dance Education, Elizabeth McLean's view was that Fedorovitch had a "formative influence" on British ballet design of the 1930s and 1940s, and that she should be considered the equal of her contemporary, Christian Bérard.
[3] Fedorovitch was born and raised in Minsk, Russian Empire (now Belarus) and studied painting in Kraków, Moscow, and St Petersburg.
[5] Costumes and scenery were by Fedorovitch, who continued to work with Ashton for more than twenty years, and became, in his words, "not only my dearest friend but my greatest artistic collaborator and adviser".
[4] In 1940, Fedorovitch did stage design and "simple but gorgeous costumes" for choreographer Andrée Howard's best known work La fête étrange, for London Ballet, based on an episode in Alain Fournier's novel Le Grand Meaulnes.
