Lena Dunham sells off sweater at planned parenthood event

Lena Dunham auctioned off the 'Madame Ovary' sweater she wore while attending the Planned Parenthood Los Angeles Champion of Choice event on Thursday (01Oct15) and had to leave in a loaned coat.

The Girls actress/writer turned heads when she turned up in the wool sweater designed by her boyfriend Jack Antonoff's sister - because it featured an image of the reproductive system.

Dunham shared the look on Instagram, adding the caption: "Rollin to the @plannedparenthood Los Angeles Champion of Choice event and there was only one sweater that would do."

And the fashion choice was such a big hit, people wanted to buy it from her.

Offering up the sweater during a charity auction, Dunham was amazed when it went under the hammer for $4,000 .

She returned to Instagram later and wrote, "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 (underwear) and a men's coat."
