For his next film ‘PK’, in which he is supposed to play an alien, the actor wanted to get the look right. The actor plays an alien who wears anything that comes his way (including a skirt) the look couldn't be too refined. During brain storming session, director Raj Kumar Hirani and Aamir Khan decided that the character ‘PK’ should be seen wearing worn or old clothes, since they are borrowed or stolen. So instead of sourcing the clothes from a designer, the duo decided to seek help from the general public, media reported.

According to media reports, before the shooting began, the crew of the film was sent on a mission to get used clothes. Aamir and Raju too 'picked up' clothes from people on the streets or their local crew. When they shot in Rajashtan, they wanted shirts in authentic Rajasthani print. But instead of going to the local market, they requested the locals to give them the clothes that they were wearing. In return, the film's crew gave them money or a new shirt. The locals were more than happy to help the film's crew. When the crew displayed the clothes they had managed to collect, Raju and Aamir were extremely pleased with the quirky collection that helped add colour to the character.

The film is being directed by Rajkumar Hirani and produced by Vidhu Vinod Chopra and Siddharth Roy Kapoor. It stars Aamir Khan as the main lead with Anushka Sharma, Sushant Singh Rajput, Boman Irani and Sanjay Dutt.

The most anticipated movie will hit theatres on December 19, 2014.
