Jemima Khan has won Halloween, three weeks before the big day.
The activist and journalist attended the annual UNICEF Halloween Ball dressed as Melania Trump being groped by her husband, the Republican presidential nominee Donald Trump.
"'Grab 'em by the pussy' #yourworstnightmare," she posted to Instagram ahead of the star-studded event in London.
Her uncanny appearance was offset by some severe smoky eyeshadow, a form-fitting white dress and a blow-up doll resembling Trump wrapping his arms around her.
"Donald, you can always grab me if you like," she said in a video posted to her 26,000 fans, doing her best Melania impression.
In a later, more disturbing frame, she cuddled up to the doll and mouthed "I love him" while a friend looked on in alarm.
Khan's costume also took aim at Mrs Trump by carrying a stack of papers on the red carpet titled: "Michelle Obama's Convention Speech".
She completed her sartorial sledge with a Trump placard that included a reference to his recent election date gaffe: "Make America great again! Trump 2016. Vote on 28th November!!!"
The US election is on November 8.
The activist has a keen interest in politics.
During her nine-year marriage to cricketer-turned-leader of the Movement for Justice Party in Pakistan, Imran Khan, she campaigned for an end to corruption for in the country.
She also set up a (now defunct) fashion label specifically to raise funds for the Shaukat Khanum Memorial Cancer hospital.
The 42-year-old returned to Britain after her divorce in 2004 and is now a contributing European editor of Vanity Fair and associate editor of the political publication, New Statesman.
