From her powder blue Jackie Kennedy-style inauguration outfit to her love of clean lines and sophisticated tailoring, she's not put a foot wrong when it comes to fashion.

Now style bible Vogue has confirmed that - after just three full months as First Lady - Melania Trump's fashion influence has already trickled down to Europe's royals - not to mention other women on the world stage, such as Juliana Awada of Argentina and Queen Rania of Jordan.

The Melania effect was confirmed by writer Edward Barsamian, who noted how Queen Mathilde and Crown Princess Mary had both adopted Melania's style on the Belgian royals' state visit to Denmark at the end of last month.

'Queen Mathilde’s periwinkle blue coat could have been pulled straight from the new First Lady’s wardrobe, and was reminiscent of the custom Ralph Lauren Collection Inauguration Day outfit,' he said.

'Much like Melania, the queen and crown princess had all the necessary ladylike accoutrements to amp up the First Lady effect: leather gloves, tonal coordinating clutch, and a pillbox hat.'

However, it's not just 46-year-old Melania's inauguration outfit that's captured the imagination of Europe's royals, according to A-list stylist Natalie Robinson.

'Overall, it appears that many European royals are finding comfort in Melania’s fashion taste as it oozes traditional glamour in a tasteful way,' she told Femail.

Melania Trump's custom Ralph Lauren blue suit, which she wore to her husband's inauguration in January 2017, is possibly the most influential outfit of the year so far according to experts

'It appears that European royals including Princess Mary of Denmark have cottoned on to First Lady Melania’s style and it's becoming somewhat contagious.'

'On a recent royal visit, Princess Mary of Denmark was spotted wearing a pale blue coat - a similar look to Melania’s pale blue dress that she wore for the Presidential Inauguration.

'Princess Mary’s coat cinched in at the waist to showcase her svelte hourglass silhouette also bears a remarkable resemblance to the style of coat Melania wore to the Women’s Empowerment Panel at the White House and for her weekend trip to Mar-a-Lago.

'First Lady of Argentina, Juliana Awada, and Queen Mathilde have also been spotted in pale blue outfits that sit just above the knee, thus replicating Melania’s understated style yet again.'

Queen Mathilde of Belgium is known for playing it safe in patterned dresses with court shoes, and ultra matchy-matchy outfits that take co-ordination to the limit.

But on her recent state visit to Denmark, she surprised royal lookers in a show-stopping red sequinned gown, revealing a shapely figure that has hitherto gone unnoticed.

'Mathilde looked sizzling hot in a red dress at The Black Diamond event in Copenhagen opting for classic Hollywood glamour,' Natalie commented.

Even the ever stylish Queen Rania of Jordan appeared to be mirroring Melania in an outfit that showcased layers of fabric around the neckline when she visited the White House last week

'Melania’s signature colour is also red, so it seems, choosing to wear the statement colour for a number of occasions.'

Another lady in red is Queen Letizia, who tends to stick to the kind of blouses and trousers and two-piece suits that were her go-to in her former role as a TV newsreader.

However, Natalie notes that she too chaneled Melania's signature colour and looked 'dangerously hot' in double red on her recent visit to Japan.

Queen Rania of Jordan recently met the First Lady at the White House, and while they went for very different colour scheme with Melania in green and the royal in black, they seemed to be mirroring each other's style.

'Queen Rania of Jordan and Melanie Trump wore similar style outfits in Washington that showcased layers of fabric around the neckline,' Natalie said.

'And let’s not forget Princess Victoria of Sweden whose tailored, cream coat suggests a more pared back style, mirroring Melania’s minimalist fashion choices.'
