Ever since Kareena Kapoor featured in her bright pink saree and dark blue blouse in her item song 'Halkat Jawaani' in Madhur Bhandarkar’s upcoming film, her costume became the talk of town. And now buzz is that the same ensemble is being auctioned for a cause.

Our source says, "The money will be donated to a charitable organisation, which Kareena is associated to." There is also news that the Manish Malhotra-designed costume managed to create quite a buzz at the recently concluded Mumbai fashion week.
