There were reports that Shruti, 30, wasn't happy with Gautami's choice of clothes for her character in the movie and brought in her own outfits.
The film will see the actress share screen space with her father for the first time.
Her spokesperson said the actress along with the movie's core team felt there was a need to add more to the clothes suggested by Gautami and it was a collective decision to redo the look.
"Styling being a collaborative and subjective effort, needs inputs from the producer, director and the actor and giving the stylist feedback, redoing looks is the standard procedure. The core team mutually felt the look needed more to be added and specific feedback was shared with Gautami," the spokesperson said in a statement.
"Being a thorough professional herself, Gautami understood and brought in a new lot of clothes which seemed to work better. Shruti in fact, added in elements from her own closet to help Gautami."
"Sabaash Naidu", a trilingual comedy-adventure, is directed and produced by Kamal.
