Melania Trump has surprised the world by visiting child migrants on the US-Mexico border — but it was her choice of clothing that stunned the Internet: a jacket emblazoned with the words "I really don't care, do you?"

A tone-deaf sartorial decision — or a hidden message from the first lady? And if so, to whom? The images of Melania Trump sporting the olive green khaki jacket surfaced as the White House struggles to calm international anger over the practice of splitting migrant children from their parents. Asked about the military-style jacket with large white brush-style lettering — apparently sold for $39 at Zara — the first lady's spokeswoman Stephanie Grisham said "there was no hidden message."
