Yes, I very well could imagine this. Geek chic is very much a thing and this would probably play just fine.
I think about this the opposite way from you: Why should having a PhD change the pressures one faces around fashionability and body image? Are you suggesting that people with PhDs have earned the right to be exempt from social pressure by virtue of succeeding in a graduate program?
Choosing some arbitrary and largely fashion-orthogonal dimension to slice up the population seems like a very reasonable way to try and advertise fashion to a wider audience. If you are decrying that the media is pigeonholing women as being more fashion-sensitive, or that they are cherry-picking some expected body type out of their chosen demographic, then that is a separate and perhaps valid issue. But I don't read this as having any bearing on the value of a PhD, except as a way to market to an audience that cares about intelligence.
Do you think that's a realistic expectation for all of society? Much less an enjoyable one?
I, for one, thought this calendar came out very tasteful, while still maintaining a feminine (even a 'strong female') message. Nobody is 'reduced' and these aren't girls in bikinis.
Loosen up a little and have a more moderate viewpoint.
Spoiler - Men (nay, everyone) are judged on their appearances in every facet of life. Look at the numbers: tall and traditionally beautiful people, on average, go further in life, purely based on their appearances. It's just human nature. But we can be a more evolved and sophisticated society by balancing our urges with an appreciation of objective metrics, not looks.
Yeah, that would be ridiculous. The only thing I can imagine more unlikely would be something like, say, the world chess champion as a fashion model. [1] [2] [3]
