After befriendingmeeting Sri Rama at Mt. Rishyamuka, Sugreeva promises to bring back Sita from whatever place she is held captive. He informs Sri Rama that he has seen Sita travelling overhead in the sky while being abducted. He also says that Sita, while being abducted, has dropped her ornaments(wrapped in her upper cloth), at his place atop the mountain.
Then Sugreeva shows the ornaments to Sri Rama, asking him to identify them. Sri Rama recognises the ornaments and the upper cloth of Sita.
Why did Sita have ornaments during the stay in exile?
