The jacket stirred intense fury, and particularly startled those on the left side of politics who had, for some reason, convinced themselves that Melania was somehow not on board with her husband's policies. "FLOTUS Jill Biden is sending out a clear message which is completely different from her Predecessor Melania Trump".
But according to Anita McBride, a former chief of staff to Mrs Bush, Dr Biden's willingness to involve herself in the shaping of the administration's policies makes her more comparable to Betty Ford: "Clearly [Biden] is an activist First Lady and is very comfortable in that".
The White House's senior associate communications director, Matt Hill, suggested that the message featured on Biden's jacket had been directed towards the military, tweeting that she was "bringing love from America, especially for American military service members and their families serving overseas".
"Melania Trump wears a hate jacket". Though the item is no longer listed on the label's website, a similar "love" jacket, in white, is now retailing for $448. Me, I'll take Love over Hate every day.
"That's an exciting part of the visit for us".
Others rushed to Trump's defense, with some claiming that her army green jacket had been a message to the press. "Get over it", one wrote.
Biden's ensemble won approval from Zadig & Voltaire's artistic director, Cecilia Bonstrom, who posted about the jacket on Instagram stories alongside the message, "Love @flotus wearing @zadigetvoltaire LOVE blazer". "'Bringing love.' *eyeroll* @MELANIATRUMP was a kind, gracious, elegant FLOTUS, who represented the USA beautifully", a third user added.
Carrying Wilfred in her arms, she and a barefoot Jill Biden also strolled along the beach in front of the summit venue in Caris Bay. "Really? When people, including Melania's fellow Europeans, compare the two, they aren't talking about jackets", another person wrote.
"Joe and I are both looking forward to meeting the Queen", Jill Biden said. "But she probably did take note that a message on the back of the first lady's jacket is noticeable & can inspire conversation", Twitter user @BetOnHumanity wrote.
"I think that we're bringing love from America", she said, when asked about the jacket.
"I think it's needed right now, that people feel a sense of unity from all the countries and feel a sense hope after this year of the pandemic".
Not all netizens, however, showed support for the first lady, expressing skepticism over her message.
Melania was photographed boarding a plane in June 2018 in the $39 Zara jacket, in the midst of national outrage over the treatment of immigrants from Latin and South America who were entering the USA, particularly children.
While their husbands held their first face-to-face talks as leaders, Jill Biden had tea with the British premier's new wife, who is making her debut in the global diplomatic spotlight. The Commission on Presidential Debates changed the format this time, muting of microphones to start each of Thursday's debate segments.
