Charli xcx and Billie Eilish are teaming up for an important cause.

The artists are donating all the unused underwear and bras from the "Guess" remix music video to I Support the Girls.

The nonprofit "collects and distributes essential items including bras, underwear and menstrual hygiene products, allowing people experiencing homelessness, impoverishment or distress to stand tall with dignity."

Charli, 31, and Eilish, 22, dropped their music video on Thursday, Aug. 1, which features a house party where the guests start to strip down while dancing. At one point, as undergarments fly, Eilish crashes through the house via bulldozer.

The artists then climb a mountain of underwear and bras in a separate location rolling around the massive pile of clothes. "We’re so lucky to be getting the formidable panty mountain!" the organization posted on X (formerly Twitter) about the artists' contribution.

Dana Marlowe, I Support the Girls founder and executive director, tells PEOPLE about the massive donation of underwear.

"The avalanche of underwear and the formidable bra mountain from the ‘Guess’ video shoot will impact thousands of survivors of domestic violence," she says. "I am so blown away by the generosity and mindfulness of Charli xcx and Billie Eilish to consider this donation to I Support the Girls."

Marlowe also spoke about the importance of these garments. "When you flee an abusive situation with nothing but the clothes you are wearing, new undergarments are a first step towards being comfortable in your own body and regaining a sense of freedom."

She continued: "Choice in what you wear is essential, and for many of our recipients, choice is a privilege. Our non-profit organization provides not only choice in what you wear, but the option to choose dignity."

"Sometimes the small things are really the big things"

She concluded: "I Support the Girls is honored to receive this donation — our Brat summer is in full swing."
