Though done differently living up to expectations such as Meena Kumari must be quite a task. All three actress have done it beautifully. Madhuri Dxit did it in Devdas, Dia Mirza for a photoshoot for Harpers Bazaar & Sonam Kapoor for Filmfare.
Madhuri also did a shot like Madhubal from mughal e azam in Devdas which was later done by sonam kapoor in filmfares photoshoot.

Here are Sonam Kapoor's interpretations of the bollywood classic beauties. I must say Sonam has done a great job of bringing back that era to life. No wonder she is the best cover girl from Bollywood.
She is in Anamika Khanna for this shoot.
I have also attached the original classics that Sonam is trying to portray for comparison.
My favorite is her portrayal of Waheeda rehman.
