Jacket: No, Jackie: Yes

Melania visited immigrant children again yesterday, this time not wearing anything that could kick up a fuss. Town & Country magazine says she was channeling Jackie Kennedy:

Her ensemble appeared to be inspired by what Jackie wore in Greece on the day before her wedding [to] Aristotle Onassis. While some of the details are different—Jackie's sleeves were short, and her feet, bare—the aesthetic is strikingly similar. (Read the article here.) 

Jackie married Onassis in 1968, in the ensuing 50 years many, many women have presumably worn white pants with a black top. High-level First Lady mind-melding or just a "casual look" coincidence? You decide.
