Her clothes which are always a source of powerful on-screen personality-transference for her has been worked on at great lengths by designer Anamika Khanna. And the result, says a member of the crew, is no less than devastating.
Apparently, Sonam was initially reluctant to get into the mature mould. "She had reservations about being bracketed in the mature mould so early in her career. In all her films so far from Saawariya to Thank You, Sonam has played a girl her own age and dressed accordingly, in what she's comfortable with. The Western clothes that 'd transform her into a chic Delhi socialite in Aisha are as much a part of her personality as the salwar-kameez that she wore in Delhi-6."
Apparently, designer Anamika Khanna, who has worked earlier with Sonam in Delhi-6, has been pouring over the designs with Sonam trying to figure out what clothes she's most comfortable in.
Shahid Kapoor, who needed to make a sartorial changeover to play the mature mellow lover in the later part of the film, has also been heard joking about how Mausam has turned him and Sonam into overnight adult stars.
Says the Mausam producer Sheetal Talwar, "Shahid has sported the mature mellow look in Jab We Met. But for Sonam the transformation from girl to woman in Mausam is a challenge. Before she left for Scotland, Sonam wanted to be completely comfortable in her new avatar."
