On the contrary,some consider the Kasta sari has fallen out of favour currently.It is considered far too revealing. It is rarely seen in the cities.This type of sari is regularly made fun of in films, portrayed as some sort of “sexy” garment, meant to titillate.In reality the Kasta sari embodies freedom for women. In a way it is similar to the dhoti as it allows leg movement and the ankles are left free. But today the Kasta sari will only be considered decent if distorted to hide every inch of a woman’s body.
Kasta saris are considered to be one of the most glamourous outfits for women in Bollywood films.Although mostly they are worn in song sequences. Generally in modern Bollywood fashion, the pallu is fully wraped around the waist rather than on the shoulder and to cover the blouse or choli, folded chunri of contrast color is pinned up.Also the hairstyle on is step-cut up to shoulder length with smart nosering or Nath and Chandrakor Bindi.
The most famous example of Kasta sari in Bollywood is the song sequence of "Humko Aaj Kal Hai Intezaar" in the film Sailaab(1990) featuring Madhuri Dixit in a yellow & green Kasta sari.  Another recent example is of Kim Sharma in the film Tom, Dick, and Harry(2006).She played the role of Bijlee,a fisherwoman for which she appeared in Kasta saris of different color throughout the entire film.
