Mouni Roy celebrated Onam in Bangalore with her mother-in-law.

Naagin actress wore a classic Kerala kasavu saree for the festivities.

Mouni’s traditional look echoed the richness of South Indian heritage and the spirit of the harvest festival.

A kasavu saree is a traditional Kerala (South Indian) garment, primarily made of white or off-white cotton or silk with a gold-threaded border called "kasavu".

Mouni Roy paired the saree with a muted grey sleeveless blouse.

Her accessories, however, stayed true to tradition. She wore intricate temple-style gold jhumkas and delicate bangles that added just the right amount of sparkle.

Her hair was neatly tied back in a sleek bun with a gajara, and her makeup was elegant and well-balanced.

Mouni Roy posed with her mother-in-law in many pictures. The actress is married to Dubai-based Malayali businessman Suraj Nambiar.
