Nudity shouldn't be a problem, it shouldn't be an issue at all. The unfortunate side of things is that we as a society have sexualised nudity to huge proportions and we're also pretty repressed meaning that the sight of a person's body is scandalous. If you want to go topless, you should go topless. Maybe put up a sign beside you that says "It's only a human body, chill the f*ck out", shame the starers a wee bit.
