Remember Sushmita Sen as the sexy and stylish college professor in "Main Hoon Na"? Now Chitrangada Singh is set to recreate the same magic as a uber chic economics professor in "Desi Boyz".

Chitrangada's character required her to look edgy, smart, stylish and yet mature. So her stylist went with fringes for her hairdo.

According to a source, a renowned stylist from London was approached to design her get-up for the film.

The look turned out to be so classic that when Chitrangada met an Indian lady, who teaches mathematics at London's Trinity College, she came and asked the actress if she was really playing a university professor in the film.

"The professor told Chitrangada - 'Well, we look nothing like you, so can I get a picture with you', " said a source.

"Desi Boyz", which also features Deepika Padukone, Akshay Kumar and John Abraham, releases Nov 25.
