Stripping down! Girls stars Lena Dunham and Jemima Kirke banded together in next to nothing for a series of non-Photoshopped lingerie portraits released on Wednesday, August 24.

The sultry photos are part of a body-positive initiative called The Lonely Girls Project, by New Zealand-based intimates and swimwear company Lonely. For their photo session, Dunham, 30, and Kirke, 31, wore lacy, see-through bralettes and panties in muted pastel colors, while lounging in bed and hanging out in a bathroom.

Dunham, who has never been shy about showing her body, has been a fan of the underwear for over a year, and posted this steamy selfie on May 25, 2015. “Love my @lonelylingerie and I think I will wear it to dinner with some boots & a smile because we are all very lucky to be free,” she wrote at the time.

Since its start in 2009, Lonely’s mission has been to create intimates for women “who wear lingerie as a love letter to themselves.”

As part of that approach, the brand vows never to alter models in their images and portray them in a non-sexual light. “Lonely aspires to showcase women wearing underwear in a way that we usually don’t see in mainstream advertising and the media,” a statement from the company reads. “Instead of being objectified, the women who participate in these campaigns — in this case, Lena and Jemima — are empowered and exhibit real beauty that will hopefully help women everywhere feel a little more liberated.”
