In May of this year, writer Gabriella Paiella called Ivanka Trump "a sentient patent nude pump." I thought about this line after Louise Linton, the wife of Treasury Secretary Steven Mnuchin, posted that photo of herself getting off a government plane. In the photo — which you've probably seen — Linton steps onto the pavement in a pair of nude Valentino Rockstud pumps.

Nude pumps signify a polished, "professional" femininity that seems to be quickly falling out of fashion. You know the look: sausage curls, heavy blush (preferably NARS's infamous gold-flecked peach shade "Orgasm"). Sheath dresses and statement necklaces and a J. Crew trench coat and a Michael Kors bag, or perhaps, if you're really fortunate, a Louis Vuitton. It's a look particularly prevalent in the Washington, D.C., neighborhoods where people "work on the Hill." It's also popular among local newscasters, Real Housewives, and female hosts of the Today show.

The women in and around the Trump administration love a nude pump. Ivanka Trump is frequently photographed wearing them, as are Melania and Kellyanne Conway. Ivanka's eponymous shoe line even features several styles in this color: stilettos, chunky heels, round-toed pumps, court shoes with pointed toes. They come in matte and patent finishes, and are supposed to resemble your skin tone.

The genius of the nude pump is how it blends the two defining traits of the "professional" costume: its high maintenance and inconspicuousness.

The best definition of the female "professional" aesthetic I've seen comes from Autumn Whitefield-Madrano. "Looking professional revolves around labor," she argues. It means getting expensive haircuts and purchasing expensive styling products, but at the same time, your hair color and style must appear "natural." It must not draw too much attention to itself, which would mean drawing attention to the labor that went into creating and maintaining it. A beehive would not be "professional," at least in the colloquial sense, nor would purple hair. Makeup is definitely required, but it must be "natural" makeup, not, say, blue eyeshadow. Having a manicure is nice, but your nails must not be stiletto nails encrusted with rhinestones. Beige or subtle pink — these are workplace-appropriate.

Looking professional is expensive, accommodationist, and emotionally taxing. Beyond looking professional, the worker (regardless of gender) must be professional. This means suppressing emotions and even opinions, and adopting a flat, "competent" affect. It means smiling but not too much. It is very complicated.

The nude pump is an ideal synecdoche for all these expectations. High heels have long been tacitly understood to be the most "professional" choice in women's footwear. Some workplaces — including those of law and accounting firms — even require them. Sure, high heels are uncomfortable and hinder the wearer's natural range of motion, and sure, they can cause lasting muscle and spine damage. But again, such consequences are a small price to pay for the right to earn a salary. The nude pump — which is definitionally the color of the wearer's skin, or close to it — draws attention away from all this. It is there, acting as a stamp of femininity, but a quiet one. A nude pump is unlikely to offend anyone. "Oh, these old things?"

This particular style of footwear seems to to have originated with upscale shoe designer Christian Louboutin. The look became popular with Kim Kardashian, Michelle Obama, and, most famously, Kate Middleton, who wore her nude LK Bennett Sledge pumps so often that The Daily Mail christened her "the reigning Queen of Nude Shoes."

So yes, the style has an unquestionable celebrity pedigree. But it also seems inextricably tied to a particular attitude towards professional aesthetics that has recently found itself degraded.

I began to notice women wearing nude pumps during Barack Obama's first term in office. This isn't just an anecdotal observation. If you look up "nude pumps" on Google Trends, searches for both "nude shoes" and "nude pumps" began to rise in 2008. Each year, searches spiked in the summer and fell in the winter. Broadly speaking, the trend seems to have reached its pinnacle in the summer of 2011, and has since been on the decline.

In fact, it was the summer preceding Occupy Wall Street that nude pumps peaked in popularity. Looking back, I think that year marked a sea change not only in leftist politics, but popular fashion, too. Occupy Wall Street was followed by the mass appropriation of feminism by popular and consumer culture, the rise of Black Lives Matter in the summer and fall of 2014, and, finally, the election of Donald Trump and the attendant mass protests.

Radical concerns and radical, in-your-face aesthetics filtered up into mass culture, including fashion. Luxury garments reading "feminist" or "smash the patriarchy" proliferated. Now, you can buy a Rachel Antonoff sweater decorated with uteruses and crocheted tampons. More subtly, the minimalist sprezzatura long popular among academics and radicals seemed to proliferate. Think all black, minimal (if any) makeup, Chelsea boots, tattoos, the odd septum ring or conch piercing. Think body hair.

Where femininity, in the traditional sense, does show up in young professional circles these days, it is often in its high form — unapologetic fuschia and berry lipstick, Dusen-Dusen-esque Memphis patterns or fruit prints. This type of femininity is unapologetically present and demands an acknowledgement of the labor that goes into dressing "like a woman."

Amid all this, what are we to make of Ivanka, the "sentient patent nude pump?" One could argue she hasn't quite gotten the memo. Women who work are simply not interested in #womenwhowork. Across America, they are shelving their nude pumps and lacing up their stomping boots.
