The women drew a crowd of over 500 onlookers when they shed their shirts and marched in downtown Portland on Saturday to promote what they call "equal-opportunity public toplessness."
Organizer Ty MacDowell said the point of the march was that a topless woman out in public shouldn't attract any more attention than a man who walks around without a shirt.
Good luck with that.
According to The Portland Press Herald, 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 warm sunny day.
"We should be able to walk down the street and not have this many men taking pictures of us," a participant shouted according to CBS affiliate WGME.
It's not illegal for a woman to be topless in public in Maine, although it is illegal in many other states.
Police said there were no incidents or arrests.
