She is human, her Achilles heel, just like RK, is her zid. This has been apparent actually from the beginning.
And I am happy for that. Happy that for once, the heroine has grey tones to her character.
When RK said, let's see what is more important, zid/akkad or the people waiting downstairs...her gaze was still stubborn. She knew she was wrong, and of course she will change the saree, because she has realised she is being adamant. Imagine, her parents have been invited for the first time to her sasural with due respect and she is still stuck to her saree, not even her saree, her souten's saree!!
