The movie, produced by Rhea Kapoor and Ekta Kapoor, has an all-female cast also including Sonam Kapoor and Kareena Kapoor Khan.
"We are going on floors in September...I am very excited. We are preparing for that. I have been instructed to lose weight, so all my hardwork and effort is in not eating food," Swara told reporters here, yesterday, as part of Asia Society's third edition of 'New Voices Fellowship for Screenwriters'.
The 28-year-old actress said the tone of the film is happy and light but it has an empowering story.
"Women have fun too, they dance, party, we all have done. It is about today's city women and their real problems," she said.
