This collection is at the same time the Theater’s wardrobe, requiring constant maintenance and security. About 1,000 costumes are worn on stage during each season. Dancers are taught how to put them on, how to tie kerchiefs in the various characteristic headdresses of each region and how to fold them properly.

Wardrobe mistresses assist dancers to dress and ensure proper maintenance and storing. Some costumes are extremely heavy, others are embroidered with gold thread.
