Doesn't matter. When I visited India, I was told by the travel agent to wear modest clothing. It's respectful to their culture. I didn't run out and buy a sari and a veil, but I did wear long skirts, long baggy pants with long tunics and sometimes I did put a scarf on my head because the sun was incredibly hot.

Oh and the fact that the men there on the street will grab at your ass if you wear immodest clothing. That's just how it is there.
