We weren't finished with Mr. Leon Bakst (1866-1924) just yet! He was a costume designer with the influential Ballet Russe (the Russian Ballets), which incorporated modern dance, exceptional music (collaborations with Igor Stravinksy among others) and costumes to create a meaningful story.
Here are some of his beautiful sketch designs:
costume for a Nymph in Daphnis and Chloe, 1912
design for Nijinksy in La Peri
costume design for a pilgrim
Bakst was also an elaborate set designer:
set design for Aladdin, c. 1916
set design for act II of Las Demeures of Phaedre, 1923
ps: a documentary was released in 2005 about the Ballets Russe, watch the trailer here.
