Melania Trump’s fashion has royal watchers comparing her to Princess Diana

Melania Trump has visited Buckingham Palace for lunch with the Queen but her choice of outfit has royal watchers comparing her to another iconic royal.

First Lady Melania Trump has arrived in the UK with her husband, US President Donald Trump for a three-day state visit.

Mrs Trump cut an elegant figure in a crisply tailored Dolce & Gabbana dress and a matching broadbrimmed Hervé Pierre hat and navy Manolo Blahnik shoes.

But there was something special about the white and navy ensemble that had royal observers drawing comparisons between Melania and Princess Diana.

It is not known whether Mrs Trump, 49, chose the outfit she wore to lunch at Buckingham Palace to pay tribute to a similar design worn by Princess Diana on the 50th anniversary of VJ Day in 1995.

Princess Diana wore several immaculate outfits in white and navy throughout the 1980s and ‘90s.

Other royal watchers noted that Mrs Trump’s fashion inspiration may have been inspired by two other “English roses:” Audrey Hepburn’s character of Eliza Dolittle in My Fair Lady; and Kate Winslet’s character of Rose from Titanic.

The President and Mrs Trump were greeted outside the palace by Her Majesty Queen Elizabeth II, Prince Charles and the Duchess of Cornwall.

It is not certain why the women chose to wear white — in celebration of summer or perhaps in acknowledgment of the suffragettes, perhaps, as was seen with Hillary Clinton and the woken in Congress who donned white for Mr Trump’s State of theUnion address.

The Queen wore a turquoise suit dress with a floral print beneath.
