As per our indian culture, after marriage, we are supposed to be "more" dignified, whether in dressing sense or how we talk.. Looks like Sonam is "least" bothered about that fact. For these celebrities, marriage is more like a 5 day "tamasha" where people spend lakhs and crores based on their financial standing.. oops ! based on fiance's financial standing. And after that, back to the same school (like how they used to be before marriage).. We copy western culture, whereas western culture praises highly about indian culture & they are inculcating our indian culture.
