The 42-year-old socialite and campaigner arrived at the UNICEF Halloween Ball at London's One Embankment on Thursday (13 October) night, dressed as Donald Trump's wife Melania, but with a risque edge.
The costume portrays two characters, Donald and his wife, Melania Trump.
While he flounders and pouts and denies these allegations as libel, activist and journalist Jemima Khan has the ideal response.
Khan posted a picture of her costume on Instagram and captioned it "Grab 'em by the pussy #yourworstnightmare".
Trump was in a controversy over the weekend.

In a later, more disturbing frame, she cuddled up to the doll and mouthed "I love him" while a friend looked on in alarm. In which he later adds, "I moved on her like a b*tch".
So in this way, Jemima Khan also took a jibe at Melania Trump's alleged plagiarism during the Republican National Convention in July this year, where Melania had apparently copied Michelle Obama's 2008 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!" reminding us that this man intends to be the next President of the United States.
The US election is on November 8.
