My take
I don't say she should not wear those blouses because they are indecent or not worn by women as a regular fashion today
these r NOT my reasons
my reason is it is NOT in keeping with the character
what is her character
a simple middle class maharashtrian girl
They may be dressing up this way for a party occasionally
but they do not wear it on a regular basis when they go to markets or vaccinating their babies or in chawls
I don't know why to justify her backless blouses it is made into a cultural issue
Rajasthani women may be wearing and in some parts of India women may be choli less too , point is Purvi does NOT live in Rajasthan
nor does she live in parts of rural India where women r choli less
she lives in Dombivli , Mumbai , Maharashtra where middle class girls from chawls DON'T wear these types on regular basis
if anyone says yes they wear i have seen etc i will strongly disagree as the Mumbai i visit and the Dombivli i visit to meet my reloatives does NOT show this picture
so i will go by what i see and experience
just as choli less women in rural india or rajasthani women will stare at a woman in mini skirts or jeans so will Purvi be stared at if she wears those blouses and shows that much back in Dombivli markets
it will look funny and odd and invite stares
So according to me it is not a culture thing at all
neither is it a sexist thing ...that should women stop wearing this and that coz men stare etc
neither is it a decent or indecent thing
for me its simply a practical thing .
Look at her character
a girl who wore salwar khameezes not even jeans
later switched to bengali sarees after marraige
then once more shifted to Mumbai and changed to Mumbai mode of dressing
nobody will say anything if she dresses up like this for DK's party
but definetely she will invite whistles and comments if she haggles with Bhaji wallahs wearing those blouses and shows so much back .
Now regarding Ovi wearing western clothes
her character is a girl from Canada , dressing that way . She was and is a model . Purvi is not and i feel her dressing is strange and not in keeping with the character .
So acc to me it is not Ovi vs Purvi , decent vs indecent , culture vs cultureless at all . It simply has to do with the character . Neither r western clothes indecent nor indian clothes , its what is appropriate in which place , thats all .
