You're right Netri, I love how they all dress so normal. Even Sanju looks so normal. It reflects reality because even rich people dress normal on a daily basis.
I think the dress designer of the show makes sure to keep the essence of the show wether its men or the ladies of the family. Very relateable outfits. Meena does look like a house helper, Gopi Kaka and Dolly Didi the same. People id Chawadi Bazaar are normal people from different background, you see people with turban or Burqah or Hijab, Dupatta, everything which you see around you. These nitty gritty things also contribute to the uniqeness of the show.
