Selena Gomez, Jennifer Lawrence, and Kylie Jenner are on the list.
We all heard about the event created in 2011 as part of Breast Cancer Awareness Month and encouraged women not to wear bras to raise awareness for the disease and support survivors.
And while many women including the female celebrities have ditched their bra to promote the cause on this special day, many stars don't hold their braless escapades for just 24 hours a year. These gorgeous celebrities let their boobs go free in public and are also garnering the attention.
Let's take a look at all the gorgeous stars who have gone out sans lingerie.
Rihanna always keeps experimenting with new appearances; there's simply no room to incorporate a bra into things; unless of course, she is wearing a bra as a top, which she does pretty well too.
Kim K remains confident about her body. She can't let anyone tell her that she can't set her girls free; even if she's attending a formal event.
How glam does actress and singer Selena Gomez look in this gold gown? Gomez has a lot of poise, and she's not afraid to throw archaic ideas to the side and strut her dress without a bra on.
Lawrence loves to dress up in designers like Christian Dior. And sometimes when the dress is form-fitting or almost there, there's just no room for a goofy old bra.
It makes no difference that Paltrow has two children, Paltrow likes glamorous, elegant and minimal looks; and by minimal, I meant that she's often spotted without the constraint of a bra.
No wonder model Miranda Kerr was at the center of Justin Beiber and Orlando Bloom conflict. She always looks flawless. She enjoys appearing in public without harnessing her chest area.
Wilde has walked on the red carpet without a bra on numerous occasions and showed the world that there is no need to cover up; even after giving birth to a son.
Heidi, even at the age of 41, continues to boast the perfect bosom. She has loads of experience rocking all kinds of different looks; even those that don't require a bra.
Kendall is used to flaunting her figure for the camera. She revealed her love for breasts, she said,"I'm weird, I love my tits being out. It's like one of my things, I guess."
Kylie likes her aesthetic to be young, fresh, and experimental; and most of the times those trendy styles just aren't conducive to wear a bra underneath.
Mariah is known for her risque outfits. She hardly has any room in her wardrobe for a bra. That's cool. She always looks amazing without one.
Lindsay Lohan has an aversion to bras. Seriously, she hates wearing them. It's like she is allergic to the support of something. So, does Lindsay even own a bra? No ways.
