I particularly enjoy how Ovi has been made to age gracefully. She seems to have a plumper face, her sarees are tasteful and that wonderful old style bun together with the hairnet is just gorgeous. She's one of the few characters who have been made to look older well.
Completely agree with this part. Ovi is looking very classy- her look is very different from the way she dressed earlier so it becomes easier for audience to identify her as being in a different age group now, at the same time she does not look 'old'. There is no over the top dressing to show her as elderly (no white in hair, no elbow length blouses, boring sarees). She looks like a successful, smart fashionable 40 year old woman, without going over the top with the fashion thingy too. Even my Mom was saying that Ovi looks very good- she totally looks her character and is playing it well.
