Scout Willis is a known advocate of the Free The Nipple campaign, and she may now be putting the spotlight on female body hair.
The daughter of action movie veteran Bruce was spotted at her London art exhibition on Thursday and seemed to have been making a statement.
The star appeared to have grown out her underarm hair, with a dark patch visible under the line of a very revealing dress.
More obviously, she flaunted her body as her boobs were almost on full display in the skintight, almost see-through gown she wore for the occasion.
Scout went braless in the nude-coloured dress, which ran down to her ankles and was teamed with black booties as she stepped out at the Impossible 8x8 exhibition, which included her own work.
She has been vocal about the Free The Nipple campaign in the past, writing an article for oxjane.com last summer in which she discussed her feelings on the issue.
She wrote: "I am not trying to argue for mandatory toplessness, or even bralessness.
"What I am arguing for is a woman’s right to choose how she represents her body -- and to make that choice based on personal desire and not a fear of how people will react to her or how society will judge her.
"No woman should be made to feel ashamed of her body."
She joins the likes of Chelsea Handler, who has also hit out at female censorship and protested when a photo challenging Vladimir Putin was removed from Instagram
She posted a topless snap on top of a horse, mimicking the Russian President's original - before hitting out at the social media site when it was banned, stating if men could be topless, why not women.
