Producer Karan Johar has asked Sonam Kapoor to shed her glamorous designer makeover for casuals in the runup to her upcoming film 'I Hate Love Stories' with co-star Imran Khan.

The 23-year-old Saawariya star, a magazine cover favorite because of her sartorial sophistication, has been told to lay off her designer gowns for debutant Punit Malhotra helmed film.

A production aide of Dharma Productions told Business of Cinema, "While Imran has a boyish image, Sonam has an international designer gown wali image. While it may have worked for her to get plush endorsement campaigns with international brands, she comes across too hip for the Indian masses. So Karan has asked her to lock away all the designer gowns and start appearing in public in casual jeans and t-shirts."

I Hate Love Stories is currently under pre-production and will begin filming from October 16.

Sonam talks about her passion for clothes shopping:

"I love online shopping. I check out the latest clothes on the internet and then I order it. When my dad came last month from Los Angeles, I asked him to pick out an outfit that I had ordered. Most of my money is spent on clothes. I think I can buy clothes everyday. In fact I lost my weight when Sanjay Leela Bhansali told me that I had to wear backless cholis in Saawariya. Anything for clothes."

Manish Malhotra will be styling Sonam in the film and she has volunteered to shop for her wardrobe with him.

I Hate Love Stories additionally stars Sammir Dattani.

Sonam is currently filming for her father's home production, Ayesha with co-stars Abhay Deol, Amita Nangia, Arunoday Singh, Cyrus Sahukar and Ira Dubey. The film is directed by Rajshri Ojha.
