I'm in India, suit wearing is not really a big cultural thing anymore (and I doubt it ever was for most people). At least if you're not a bureaucrat.
No, what I mean is people finding other people in suits attractive is a cultural thing across the world. I am also from India.
In many places being a bureaucrat is exactly the impression you will make, wearing a suit. Depends on the individual, whether they want that. As an engineer I wouldn't want that.
