"She always looks like a high priced call girl in her tightclothes and stiletto heels with that icy cold smile that never reaches her eyes."

That's the second-highest-rated comment at "Photos of Melania Trump donating her inaugural ball gown to the Smithsonia" (WaPo).

The highest-rated comment is: "Remember when Michelle Obama going sleeveless was a scandal? Republicans have ridiculous double standards." To answer that question: No. But if it happened, I'll bet it was in a different situation, like inside a church, and not at a ball.

Here, I found this from March 2009: "Obama's Choice to Bare Arms Causes Uproar." There was some criticism of Michelle Obama for going sleeveless in her first official photograph as First Lady and at Obama's first congressional address, which took place in wintertime.

"Most of the complaints centered on the dress conveying a sense of informality on a serious occasion," [Chicago Tribune style reporter Wendy] Donahue said. "She's kind of faced some criticism for that in the past where people have said maybe [her clothing is] distracting from the central point, from what is going on."...

"When she was at the non-State of the Union address and had the sleeveless dress on, that was a bit of a surprise and I got some e-mails from some folks who were, you know, they work on the Hill and they were like, 'Wow she's sleeveless,'" [Politico White House reporter Malika] Henderson said. "'Nobody else is sleeveless here and it is the winter.'"

I don't think anyone criticizes a ball gown as informal when it bares the arms (and shoulders and much of the back and chest). Those are standard design attributes that make it seem formal.  The bareness is standard even in winter, and I don't think Michelle Obama was criticized for baring her arms at the inaugural balls.

But if you want to talk about double standards, I don't remember anyone saying that Michelle Obama looked like a "call girl in her tightclothes and stiletto heels with that icy cold smile."

Was Obama criticized for wearing her clothes too tight? Yes! In the New York Times, quoting an unnamed fashion designer: "Her clothes are too tight."

Was her smile criticized? Yes, according to "To the First Lady, With Love Four thank-you notes to Michelle Obama, who has spent the past eight years quietly and confidently changing the course of American history," in the NYT just before last fall's election:

Because she said what she thought, and because she smiled only when she felt like smiling, and not constantly and vacuously, America’s cheapest caricature was cast on her: the Angry Black Woman. Women, in general, are not permitted anger — but from black American women, there is an added expectation of interminable gratitude, the closer to groveling the better, as though their citizenship is a phenomenon that they cannot take for granted.

“I love this country,” she said to applause. She needed to say it — her salve to the hostility of people who claimed she was unpatriotic because she had dared to suggest that, as an adult, she had not always been proud of her country. Of course she loved her country....
