Even for the lionhearted, skydiving can already be a nail-biting feat that remains beyond the reach of bravery.
But skydiving in your underwear? Now that's taking mortification to a whole new level.
This month, two women in California are throwing caution to the wind, however, and taking a dive from the heavens in nothing but their lingerie -- all in the name of overcoming fear, ABC reports.
As part of their photography company's "Be Bold. Take the Leap" initiative, photographers Jennifer Hoffman and Marisa Gallegos of Esme & Eve will be joining five other women in jumping from an airplane near Lake Elsinore, Calif., on Nov. 17.
They will be fitted in nothing but their undies -- and a parachute.
Esme & Eve's "Be Bold" initiative urges women to "face their fears, take a risk, and push against whatever it is that is holding them back from carrying out their dreams," according to the group's Indiegogo page.
"We feel that the parameters of what makes today's woman feel valued need to change in a very, very big way. We see how narrow, convoluted standards stifle so many women from achieving their potential and we strongly believe that is intrinsically wrong. We want more women to shed the mantle of what binds them to ideas that do not serve them," Hoffman told SheKnows.
This will be the second time that Hoffman and Gallegos do a lingerie skydive, but this time they have invited a number of other women to join them.
Each of the women participating in the jump has experienced trauma in her life. The five participants include a rape survivor and a woman who has overcome an eating disorder.
"All these women have terrific stories," Hoffman told ABCNews.com. "I get really motivated by these women. We all follow the tragedies of our lives, but we don't follow the triumphs. We want to highlight the triumphs.
"We really wanted to make sure we had women with different stories that people can resonate with. I know how much one person can change another person's life, and we're just trying to do that on a smaller level. I don't expect any massive change happening out of this, but I would love for it to have a ripple effect," she continued.
