If you're feeling like a boob these days, Sunday might be a day for celebration.
August 25 has been declared Go Topless Day, a 24-hour period where ladies are encouraged to show their breasts as a protest against hypocritical laws that allow guys to walk around shirtless while women must remain clothed.
Men who support the group's mission are asked to cover their own man-boobs with pasties or bras.
This year marks the sixth anniversary of Go Topless Day, which is organized by a group of UFO believers called the Raelians.
Members believe that humans were created by advanced scientists known as the "Elohim," and that not allowing women to go topless is an insult to the aliens' artistry.
Go Topless Day Organizer Nadine Gary, a Raelian priestess, told The Huffington Post that it's not a problem getting men to participate.
"The men love to support us," she told The Huffington Post.
Forty cities, including Vancouver, San Francisco, Los Angeles, Miami, Detroit, Denver, Chicago, New York and Washington D.C., will be holding demonstrations, up from 30 last year.
The holiday was launched in 2007, when activist Phoenix Feeley won a lawsuit against New York City after she was "wrongfully arrested" for going bare-chested, Gary told HuffPost. Female toplessness is legal in New York City, and so the city ultimately awarded Feeley $29,000 in damages for their mistake.
The fight for freedom still has a long way to go, though. Feeley was recently jailed she refused to pay an $816 fine for going topless on a New Jersey beach, CBS New York reported.
Male toplessness for men has been legal in New Jersey since 1936, Gary said -- but not for women.
"Why this repression?" she asks. "Are breasts dangerous? No! Breasts for something for feeding, for nurturing."
Go Topless Day is held on the last Sunday in August as a tribute to August 26, 1920, the day women finally had the right to vote.
"I don't understand these repressive laws," Gary said. "Is it because of this myth of original sin? Because women have somehow tempted men?"
