She essayed the role of a Bengali in Piku for which she beautifully got into her character. While Deepika learnt a little Bengali and worked on her diction as well, she also learnt the nuances of her character.
She even moulded her look according to that of a Bengali girl. From her dressing to her make up, she looked every bit the Bengali girl.
One of the things Deepika learnt in her Bengali transformation was how to do the typical Bengali kohl look. She learnt how to apply kaajal and liner the way Bengalis do.
She now does her eye make up in that way sometimes and she loves the way her eyes look then.
