Apparently, Vidya invested two weeks in trying the looks. "She underwent 122 changes, out of which around 12 were shortlisted. Each look required her to wear a different costume and sport complementing make-up. She would try six to eight looks every day and was extremely patient while selecting which ones fit the narrative of the story," says a source close to the film’s team. This long process of shortlisting the looks has also been documented by means of photographs. "She tried the garb of a teacher, a fisherwoman, a dabbawala and a peon, to name a few," informs the source. Ask the film’s producer, Dia Mirza, about the painstaking process and she says, "It was one fun-filled experience of discoveries and experiments. Our costume designer Theia Tekchandaney and our make-up artiste Vidyadhar worked tirelessly to conjure looks that would be entertaining to watch, whilst remaining in sync with the demands of the script. I am thrilled and wowed by the many transformations of the versatile Vidya Balan."
