In a brain storming session, Raj Kumar Hirani and Aamir Khan decided that the character of PK should be seen wearing worn or old clothes. So, Raju and Aamir came up with the idea of sourcing Aamir's clothes from a different place this time.
For the first time ever, the makers picked up clothes from random people on streets of the places they shot at. For instance, while they shot in Rajasthan, they wanted Aamir to wear the authentic print of Rajasthan. So the team got down on the streets and requested common men to give interesting shirts that they had worn in return for money or a new shirt.
Surprisingly the strangers were very supportive and happily gave their shirts to the team. When the entire collection was displayed in front of Raju Hirani and Aamir Khan, they were very pleased with how different and quirky they all looked.
