People are just realising why Melania Trump’s outfit during first day of UK visit looks so familiar

Donald and Melania Trump touched down in the UK for their second state visit on Tuesday (16 September) - and everyone is saying the same thing about the First Lady's outfit.

The US president, 79, and Melania, 55, arrived shortly after 9 pm last night, after travelling to Stansted Airport in Air Force One, and are set to spend two days in Britain.

The American couple will be spending time with King Charles III and Queen Camilla, as well as Prince William and Kate Middleton, at Windsor Castle.

As well as a series of non-public-facing engagements lined up with the British royal family, Trump is also set to visit UK Prime Minister Keir Starmer’s country residence, Chequers, on Thursday (18 September).

UK Foreign Secretary Yvette Cooper met Trump and Melania as they were pictured departing the plane, while RAF personnel from The King’s Colour Squadron lined up to form a guard of honour.

The President arrived wearing a navy blue suit, a white shirt, and a red tie, layered with a long black coat, while holding hands with Melania, who looked stylish as she stepped out, dripping in designer gear.

Melania sported a long tan Burberry trench coat, large black Saint Laurent sunglasses and black leather riding boots by Christian Dior.

However, her fashionable outfit seems to have reminded people of something, who have taken to social media to point out the comparison.

People think that Melania's outfit choice actually resembles a spy - specifically, the fictional character Inspector Gadget, who is also known for wearing a long trench coat.

One Twitter user posted a picture of the First Lady next to one of the character, writing: "Who wore it better?"

Meanwhile, a second person joked: "She's on an overseas mission," and a third questioned: "Is that Melania or two kids in a trench coat?"

And others kept up the joke, chiming in with: "How many people are hiding under that coat?" and "Spy Coat."

But it's not the first time that Melania has been compared to someone else due to her fashion choices.

Back in January, fans compared another of her looks from her husband's inauguration, including a large hat that covered her eyes, to none other than Beyoncé's iconic 'Formation' outfit.

And this time, the spy link isn't the only thing that's garnered attention - the 'fake Melania' conspiracists have also come back out, claiming that the person pictured is actually a 'body double'.

For those unfamiliar with the wild proposition, it has long been joked that many of the First Lady's public appearances aren't quite as they seem, and that Melania has actually been swapped out for a body double.

And the long trench coat and large sunglasses have fuelled the theory more than ever, with people writing: "Which Melanie is this?

"It doesn't look like Number 1", and “Hmmmm. Big smile and holding hands...must be ‘public trip’ stand-in Melania."
