Away from the typical salwar-kameez clad look, she will now be seen in western clothes.
The show revolves around parents' efforts to give childlren the right upbringing.
Shweta has so far been shown as a strict mother wearing only Indian attires. But of late, a new entry on the show, Mandira, played by actress Kamya Punjabi, is being seen as a modern-day woman - a lady who leaves Shweta's onscreen husband Lucky and son Rocky impressed.
Shweta said she had to work on her makeover.
"I had to spend a lot of time in curling my hair and the picking up accessories for my new look in the show. It is not like I don't wear this kind of dresses in my daily life, but I hope I get to go back to the earlier look soon," Shweta said in a statement.
It will be interesting to see if Shweta's new look will change her attributes of a strict and nasty mother.
