The film is directed by Anaita's husabnd, Homi Adajania and it revolves around the lives of three friends - Veronica, Meera and Gautam - played by Deepika Padukone, Diana Penty and Saif Ali Khan respectively. "Cocktail" is releasing Friday.
"The characters were defined nicely by Homi. He was very clear on the characters and gave us a lot of information on the personalities of these characters. And having all that information, it was easy for us to understand how they would dress," Anaita told IANS.
Talking about the characters, the designer describes Veronica as the most fashionable in the film, while Meera is a shy person.
"Veronica is a very fashion forward person. She loves fashion and is happy to flaunt her body. It was like mixing high street fashion with luxury designer labels as somebody like her would do," she said.
"While Meera is a simple girl who came from Delhi to London. she comes in her Indian clothes but slowly adapts to western clothes. She is not one to flaunt skin and is shy. So even in her western wear, the choice of clothing is conservative," she added.
Anaita has previously designed for movies including "Dhoom 2", "Love Aajkal" and "Ra One", apart from styling for advertisements.
She says that designing for movies is "toughest" and added: "I enjoy every aspect of styling which I do, be it for Vogue (magazine) or advertising styling. The only taxing thing about films is time commitment. I hate being tied down to such long commitment. But I enjoy if the team is organised."
