"My character in 'Aisha' is quite flamboyant and wild. So my clothes required to be bizarrely quirky and bold. Fashion is a huge element in 'Aisha', " Ira told on the phone from Mumbai.
She added: "I was told that whichever clothes you see on the ramp and say - 'Who will wear that?' - that's the confidence that my character Pinki Bose must have."
So, she did just that.
"My own personal style of dressing is very experimental. I like to have fun with my clothes. One day I came back from my trials and told my elder sister Neha that I have to wear really bizarre clothes for 'Aisha'. She said: 'That's easy because it will be just like you!' Then I told her it is 20 times more bizarre than I can get!" Ira said.
"There are clothes in funky and bold colours and they are really short. I keep joking that I'm almost half-naked in the film. There are really short pairs of shorts and I wear a bikini in a scene where we play beach volleyball, " she said.
"In 60-70 percent of the film, I am wearing shorts and wear one or two skirts as well, " added Ira, who insisted on wearing spectacles in the film to add zing to her character.
The 26-year-old theatre actress said she has developed a brave fashion sense after "Aisha", which is based on Jane Austen's popular novel "Emma".
"I have definitely become braver in style. I have a very petite frame and my co-actors used to keep saying 'you can carry them off well'. Even though I do wear a lot of funky stuff, I haven't been very bold, " she said.
"But I guess now I am a little more confident on that front, " said Ira, who requested producer Rhea Kapoor to let her keep a pair of chic navy blue boots that she wore in the film.
Before "Aisha", Ira featured in Rohan Sippy's "The President Is Coming" and also was a movie critic for Sony Pix's "Chicks On Flicks".
At the moment, she is "a bundle of nerves" and hopes she does not get typecast in Bollywood.
"It's very easy to get typecast in the Indian film industry. In my last film 'The President Is Coming', I played a sophisticated upper class girl. In 'Aisha' also, I play someone who likes high-end things. But now I really want to work with directors like Anurag Kashyap and Vishal Bharadwaj to play more grounded roles, " Ira said.
"I've done many strong, female-oriented roles in plays, so I am capable of doing simpler looking, tough roles and prove that I can handle a whole lot of diverse work, " she added.
"Aisha" also features Sonam Kapoor, Abhay Deol, Arunoday Singh and newcomers Amrita Puri and Lisa Haydon. Ira plays the role of Pinky Bose, a filthy rich girl who is best friends with Sonam's character Aisha.
