Bras and Rain Scenes



Something I'm sure most here have noticed at some time or another, is that in most Hollywood movies during romantic rain scenes women rarely wear bras. Sex sells.

In nude scenes it's seems like it would be easier to talk about with actors as it's generally clear in the script what's required and what's not. How would you talk to an actor about what they're comfortable with on this subject though?

I'm sure someone's going to reply "just keep everything covered" but I'd rather be able make choices based on what I think is right for the scene and what actors are comfortable with given a choice. Making a choice just because I didn't know how to bring something up isn't how I like to make films.
