Fair to say, you are entitled to your opinion but let me present a few different perspectives:

Men have conveniently adopted trousers and moved away from dhoti(s). I suspect this, in part, was driven by everyday work needs.

Women, thanks to their determination, have expanded their portfolio and are involved in larger schemes of society. Hence, new set of needs is generated which in turn propels change.

Finally, a counter argument lies in the negative of your final statement, "become modern by their clothing....not by clothing".

A tiny aspect of what you have placed here may be true - for men and women- but it is NOT the driver of the phenomenon.
