I seem to recall that David Byrne wrote a long blog entry about Orthodox Jews complaining when a bike path was opened up in their neighborhood because they didn't want to be subjected to the sight of IMMODESTLY DRESSED LADIES, but that's all I know about that. (I did like that his point was basically "You live in a population of other people. Sorry, but you're gonna have to accommodate them.")

I suppose there's a question of the right clothes for the right occasion, but that seems to be mostly about the clothes indicating what you're up to at any given point. Social rules and codes and all that. It doesn't have to be about sex.
