Draupadi and the Pandavas in disguise
in King Virata's court.
For more about the year of disguise in Virata's court, see Wikipedia. There is an entire article about Arjuna's disguise as Brihannala at Wikipedia. Yudhishthira disguised himself as Kanka, an expert at dice; Bhima as Ballabha, a cook; Nakula as Granthika, an expert in horses, and Sahadeva as Tantipala, an expert in cows. Draupadi posed as Sairandhri, a hairdresser.
