Lena Dunham’s relationship with Twitter might be cooling down, but she’s still very involved with Instagram. The star stripped down to her bra on the social media platform, all for a great cause.

Dunham attended the Planned Parenthood Los Angeles Champion of Choice event Thursday, and her outfit championed female reproductive rights. Dunham wore a wool “Madame Ovary” sweater by Rachel Antonoff (her boyfriend’s Jack Antonoff’s sister) emblazoned with a uterus on the front. (Interested? You can buy the $200+ design here!)

“Rollin to the @plannedparenthood Los Angeles Champion of Choice event and there was only one sweater that would do @rachelantonoff 💋” Dunham shared of the look on Instagram.

And it looks like the event was so successful, that the Girls creator left without her shirt, auctioning off the design for $4,000!

“The @plannedparenthood event in LA tonight was so crazy inspiring. I also spontaneously auctioned the ovary patterned sweater off my body for a nice 4k to benefit PP… Had to walk home in my skivvies and a men’s coat #worthit #onbrand #standwithPP,” she captioned her topless shot.

Earlier this week, Dunham revealed she made the decision to step away from her Twitter account.

“I didn’t want to cut off my relationship to it completely, but it really truly wasn’t a safe space for me,” she said, adding that verbal violence and body-shamers on the social media platform led her to leave her Twitter account to someone else to run.

What do you think of Dunham’s impromptu auction? How about her sweater? Sound off below.
