The authorities in Saudi Arabia are investigating a young woman who posted a video of herself wearing a miniskirt and crop-top in public.
The women, a model called "Khulood", shared the clip of her walking around a historic fort in Ushayqir.
The footage sparked a heated debate on social media, with some calling for her arrest for breaking the conservative Muslim country's strict dress code.
Other Saudis came to the woman's defence, praising her "bravery".
Women in Saudi Arabia must wear loose-fitting, full-length robes known as "abayas" in public, as well as a headscarf. They are also banned from driving and are separated from unrelated men.
In the video initially shared on Snapchat over the weekend, Khulood is seen walking along an empty street in a fort at Ushayqir Heritage Village, about 155km (96 miles) north of the capital Riyadh, in Najd province.
Najd is one of the most conservative regions in Saudi Arabia. It was where the founder of Wahhabism - the austere form of Sunni Islam that is practised by the Saudi royal family and religious establishment - was born in the late 18th Century.
The video was quickly picked up by Saudis on Twitter, where opinion was divided between those who believe Khulood should be punished and others who insisted she should be allowed to wear what she wanted.

Another user https://twitter.com/alotibi_it/status/886638195689099264: "We should respect the laws of the country. In France, the niqab [face-covering veil] is banned and women are fined if they wear it. In Saudi Arabia, wearing abayas and modest clothing is part of the kingdom's laws."
The writer and philosopher, Wael al-Gassim, said he was "shocked to see those angry, scary tweets".
"I thought she had bombed or killed somebody. The story turned out to be about her skirt, which they did not like. I am wondering how Vision 2030 can succeed if she is arrested," he added, referring to the reform programme unveiled last year by Saudi Arabia's newly-appointed 31-year-old Crown Prince Mohammed bin Salman.

Some defended Khulood by noting that US President Donald Trump's wife, Melania, and daughter, Ivanka, had chosen not to wear abayas or headscarves during a visit to Saudi Arabia in May.
Others wrote that had the woman been a foreigner, people would be talking about her beauty, but because she is Saudi, they are calling for her arrest.
On Monday, the Okaz newspaper reported that officials in Ushayqar had called on the provincial governor and police to take action against the woman.
