As the first official trip of President Donald Trump came to an end, there were several memorable moments of the tour like his white-knuckled handshake with the French President or his NATO speech, but what caught most of the people's attention was the first lady Melania Trump's mannerisms and well-thought dress codes.

From the moment Melania stepped off the plane in Saudi Arabia, it was evident she had thought over her wardrobe with great detail and used fashion diplomacy tactic that worked well for her predecessor, Michelle Obama too. Melania's flowing black jumpsuit designed by Stella McCartney resembled abaya, a traditional robe garment worn by Muslim women in the region, reports said.

Similarly, in Israel, Melania donned a white outfit, a color considered by Jews to be sacred, and a symbol of purity and peace. While heading to the Vatican, she chose to wear a formal black lace with a head veil. In Brussels, she wore a tan suit made by a Belgian designer, and while in Italy, the first lady stuck to outfits by Italian fashion house of Dolce & Gabbana.

“Historically, first ladies have made a difference on a trip like this,” the New York Times reported citing Michael Beschloss, the presidential historian.

Melania charted out her own schedule for this trip, different from Donald Trump, which she had announced ahead of time in a White House statement.

"Of course, as the first lady, on trips like these, she's going to go off and do things on her own," Anita McBride, who served as chief of staff to first lady Laura Bush in the White House said, adding "But she went so far as to set the marker even before she left," reports said.

While in Rome, Melania visited a children's hospital where she spent time talking to a boy who was waiting for a heart transplant surgery. A few hours after she left, she was told a donor had been found, the Times reported. “Receiving that news is a moment I will never forget,” she said adding “I wish him a speedy recovery.”

"She's already shown that although public speaking might not be something she's entirely comfortable with just yet, the actions she does take are genuine, and a window into the kind of person she is," McBride said. "She clearly and very carefully selected what she wanted to do and where she wanted to go on this trip, consistent with the types of activities she's done back at home. She's choosing things where it is something she cares about," she further said.

During the nine-day of the foreign trip, the 47-year-old Slovenian-born former model showcased her side that people had never seen before. Melania exerted her visibility at this trip, which gave the public a glimpse of what kind of the first lady she would be and where her priorities would lie, reports said.
