In the event that you ever wanted to walk around with your ta-ta's hanging free, you're in luck Monday. July 9 is national No Bra Day, according to a No Bra Day Facebook page created by Anastasia Doughnuts.

What exactly is the point of women freeing their breasts?

Ladies, free your breasts for 24 hours by removing those dreadful (but at times oh-so-helpful) bras. Our perkiness should not be hidden. It is time that the world see what we were blessed with, the page exhorts. Your breasts might be colossal, adorable, miniature, full, jiggly, fancy, sensitive, glistening, bouncy, smooth, tender, still blossoming, rosy, plump, fun, silky, Jello-like, fierce, jolly, nice, naughty, cuddly. ... But the most-used adjectives to describe your breasts on July 9th should be joyous, wild, and spectacular.

More than 250,000 responded on Facebook, saying they would be attending the event, and even though it sounds like a joke, it's quite serious for some.

A Huffington Post blogger, Hallie Seegal, went without her bra last July, relished the moment, and decided to stop wearing bras for good after she was able to become comfortable with her small breasts.

It was as if I had finally opened my eyes. That was that. Since then, it's just been me and my small boobs, hanging out together. And I'm happy, she wrote.

Women have taken to Twitter to share their feelings on the holiday.

TheBarbieMarley wrote, TODAY IS NATIONAL NO BRA DAY!! UNLEASH THE BEASTS and kiramakinsie tweeted, It's National No Bra day? I wish that was everyday. I hate wearing bras.

Of course the fellas are also in support of national No Bra Day. One addemkay shared via Twitter, I hope everybody's enjoying National No Bra Day. Let freedom swing!

But not everyone is happy about national No Bra Day. Victoria's Secret sent out a tweet, Today is apparently National No Bra Day and, we're in denial.

This is the second year the national day has been celebrated, Yahoo reported.

It's not clear precisely who is behind the event except for the anonymous user, Anastasia Doughnuts, who posted the event on Facebook. Is she paying tribute to the 1960s feminists burning their bras, or is she helping to raise awareness for breast cancer? Either way, the response to the national holiday seems to be light-hearted, with many lols posted.

One who might disagree is comedienne Tina Fey.

This is what I tell young women who ask me for career advice....I encourage them to always wear a bra, Fey wrote in her book Bossypants. Even if you don't think you need it, know what? You're never going to regret it.

The Facebook page does hint at breast cancer awareness, as one anonymous user added at the bottom, Breast cancer is something you should take seriously and be checked for, but then also adds, P.S. Ladies.... Wearing a white t-shirt on this day is not only acceptable, but encouraged!

What do you think of national No Bra Day? Is it a joke, and (if you have breasts) do you plan on participating?
