Melania Trump just gave the world a lesson in the ambiguity of clothing as a language — even when it contains literal words.

The former fashion model understands the substance of style, and she undoubtedly knew that her back would be particularly visible as she mounted the airplane's steps.

So why, on the way to visit a shelter for migrant children separated from their parents at the Texas-Mexico border, would she wear such a thing?
