"Manish Malhotra is designing the costumes of Hrithik and Kareena for 'Shuddhi'. Since it's a period drama a lot of detailing will be done in terms of costumes," Karan Malhotra told IANS.
The film is apparently set in period of 1920s and 1960s and the director says a lot of research work is going on.
"A lot of research work is going on but I can't reveal the exact eras in which the film will be shot. It's too early for that. Basically, it's a love story," said Karan, who last directed 2012 released film "Agneepath".
