Kangana Ranaut has worked hard on her look for Once Upon A Time In Mumbai. Dekho!

Sensually dramatic
The actress, who is known to reinvent herself for her roles, combines sensuality with drama for her styling for this set-in-seventies flick directed by Milan Luthria and produced by Ekta Kapoor.

"There is a lot of her in the character, " says Luthria. "She lends herself because she has a great body which does not look vulgar and her face is chameleon-like -- she can change into different looks everyday!"

Kangana plays a Bollywood diva called Rehana who is bohemian in character. Sparks fly when she meets a gangster Sultan (Ajay Devgn). Their relationship is a turning point in the film's plot.

"As it was the time of flower power and when women were getting liberated and live-in relationships came out in the open, her styling reflects all these aspects, " adds Luthria.

Her costumes have been designed by Manoshi Nath and Rushi Sharma.

The actress also did a lot of homework for the role. "We not only looked at actresses of the '70s here but also the trends that were prevailing in the West at that time.

But Kangana arrived at the office with a spiral bound book of her research for the movie. She had prepared a detailed account of the style, hairdos and accessories scene-by-scene which was also incorporated for her look."

Once Upon A Time releases on July 30.
