The 47-year-old was spotted wearing a skirt and blazer during the film shoot and also carrying a radio in his hand.
It has now been revealed that the radio was bought from Chor Bazaar and has been used on Aamir's request.
According to a source, "Aamir had seen the radio in olden times and was very keen to have it. He vaguely described it as one of the oldest radios."
The source also said that the production team had a hard time finding the radio. They not only researched, but also asked a lot of people around. Finally, they managed to get it from Chor Bazaar.
