I was in Mumbai last month for the wedding of a very dear friend's daughter.
I wore my Nehru style suit for the actual wedding ( I hate collars and ties

99.9% of the women wore Indian style as did my wife (she was born in Bombay, as it then was) 99.999% of the men wore western dress and until two MPs turned up I was the only one wearing Indian dress,
I received a number of compliments as it was appreciated that a westerner would wear Indian dress in India.
