Organizer Ty MacDowell said the point of Saturday's march in Portland was that a topless woman out in public shouldn't attract any more attention than a man who walks around without a shirt.
The Portland Press Herald reports that by the end of the march, more than 500 people had amassed - a mix of marchers, young men snapping photos, oglers and people just out enjoying a sunny, warm day.
It's not illegal for a woman to be topless in public in Maine, and police said there were no incidents or arrests.
