I think they give her the big earrings bc they want her to look like a jeweler's wife. This is still ITV and its RARE that the FL's aren't decked out in things IRL we'd wear to a dinner party or celebration etc.
I watch PS and one of the girls' kameez sets are things I'd wear on Eid bc of all the sequins, net dupatta, etc. Homegirl wears this as her daily attire. I think it's rare that ITV shows show leads in simple clothing that actually match day to day style of the average person.
Regarding her sarees in general - Yeah I'm over the "silk"/handloom. It ages her too much. Her old solid silk/satin ones or georgette ones were nice. But now that she's a bahu, she can't dress that simply either. Of the ones she's been wearing now, her floral organzas and the solid georgettes with the single trim are the nicest. The hot pink net ones have to GO. I'm ok with pink in general though because it looks good on Shivangi. But she could pull off soo many colors, it's like, give her some more variety.
I get why she wears sarees though - her character loves sarees & the tradition and culture behind them. We won't ever see her in western clothing unless they're on vacation or something.
I actually don't mind Raghav's style. Three piece suits are a bit much but I see men in that all the time, daily, esp if they're into fashion. It's not too far of a stretch IMO. Once in a while they could show him without the vest though. And I don't like every suit combination, but overall he gets dressed well IMO.
