'Go Topless Day' in San Antonio on Sunday is certain to bring out the gawkers, but organizers say it has a very serious purpose, and that is to  call attention to gender discrimination, Newsradio 1200 WOAI reports.

  Women will gather downtown and will walk around without any blouses or bras on.

  Organizer Donna Newman says it is clearly unequal and unfair to require women to wear tops in public while men don’t' have to.

  "I've seen men who have bigger breasts than some women," she said.  "They're flopping around out there and it's legal."

  The event has been held in Austin the last several years, but Newman says San Antonio's laws are stricter.

  "What we're fighting for in Go Topless, is, if a man can be topless anywhere, I should have the same right as a man, if we are really equal."

  She says another goal is to 'desexualize' breast feeding.

  She admits that some guys will show up to gawk and may not understand the social and cultural significance of 'Go Topless Day.'

  "I think it's a little bit on their part, they need to grow up a little bit," she said.

  Police haven't said how they will respond to Go Topless Day, but the women will clearly be breaking the law.

  Sec. 21-22 of the San Antonio City Code, says 'it shall be unlawful for an individual to intentionally or knowingly appear in a state of nudity in a public place,' and it defines nudity as 'the appearance of the bare buttock, anus, male genitals, female genitals, or female breast.'

  The City Code also outlaws 'semi nudity,' and it has specific descriptions of what constitutes semi nudity which are inappropriate for a family web site.

 "Public place shall mean any public street, sidewalk, alley, or other public thoroughfare, in or such close proximity thereto, as to be observed the public traveling on such street, sidewalk, or other thoroughfare, and/or all locations owned by or open to the general public inclusive of the sheds, enclosures, buildings, improvements and fixtures upon the location."

  So these ladies might be in big trouble.
