"It's quite colourful and one looks cool in a bell-bottom and a tight shirt, " Ajay told reporters after distributing the uniforms to couple of ushers.

Asked if he things that this film will inspire to bring back the style of the 1970s, he said: "We can only hope."

Produced by Ekta Kapoor's Balaji Films, "Once Upon A Time In Mumbai" features Ajay as underworld don Haji Mastan while Emraan Hashmi essays the character of Dawood Ibrahim.
