WWD retreats into quoting Anna Wintour (who is not only the editor of Vogue editor but also the artistic Director of Condé Nast of which Vanity Fair is a part). Wintour only made a gentle gibe, "I’m not sure if I should include a new pair of tights in her welcome basket."
I'm more interested in interpreting the metaphors. What can you say about a navy blue dress strewn with zippers? It says women have the power now. The zipper's strongest association is with the fly on a man's pants. We might say a man with uncontrolled sexual compulsions has a "zipper problem," as in "Jackie Collins Knew Bill Clinton Had A ‘Zipper Problem’" (HuffPo, 2011)("I remember, before Clinton was president, I was sitting at a dinner in Beverly Hills and one of his aides was there and told me that he was definitely going to be president, except for one problem: the zipper problem.... They knew way before he was elected!").
And then a navy blue dress... I think of Monica Lewinsky.
That dress was strewn with Bill Clinton's genetic material.
Therefore I interpret Radhika Jones's dress as wry political commentary: the end of the political subjugation of women, the end of silencing — zip your lip, not mine — and a new era of female domination.
Now, let's consider the item of clothing that was even more attention-getting and metaphor-pushing than a blue dress strewn with zippers: tights covered in foxes.
What do foxes mean? When the political website FiveThirtyEight chose a fox as its corporate logo, Nate Silver quoted the Greek poet Archilochus: “The fox knows many things, but the hedgehog knows one big thing.”
So there were many zippers on the dress and many foxes on the tights, which is a message of multiplicity already. But each of the many foxes is also a symbol of knowing many things.
There is, of course, the idea of women as "foxes," which was already laughably sexist when Dan Aykroyd and Steve Martin played Festrunk Brothers in 1978 (and Garrett Morris had to explain that you can't talk about American women like that):
I'd say the foxes on Radhika Jones's tights represent a reclaiming of an old diminishment, amplified and multiplied, and complicated by zippers. Foxes run around, finding out about everything, uncovering what is hidden, and zippers enclose while suggesting a sudden, perhaps shocking disclosure. That's all very apt as a message about journalism, and it's an exciting way to say that a woman is now in charge.
ADDED: Also consider that the top-rated meaning for "zipper" at Urban Dictionary is: "A death trap for your dick."
And I created a "zippers" tag and went back and applied it to old posts. I was amused by how many times over the years I've talked about the Brian Regan comedy bit about Zipper, the bad dolphin (in contrast to Flipper) — "Zipper's surly. He is uncaring."
Meade, reading this post, said his first association with zipper was the "zipless fuck" (in Erica Jong's "Fear of Flying"). I had to do some additional retroactive tagging, because I'd only searched for "zipper." Searching for "zipless," I found places where I'd talked about Erica Jong's idea, including one in the context Trump's "Access Hollywood" remarks, from October 8, 2016 (the day after the sudden, shocking disclosure of the tape):
[I]f you watch the whole video, you see him winning with another woman, Arianne Zucker, the one who, in Trump's words, is "hot as shit, in the purple." Zucker is the one who inspired him to say "I’ve got to use some Tic Tacs, just in case I start kissing her. You know I’m automatically attracted to beautiful — I just start kissing them. It’s like a magnet. Just kiss. I don’t even wait. And when you’re a star, they let you do it. You can do anything.... Grab them by the pussy. You can do anything."
And in fact, you see the female version of that power trip: The woman plays on the man's sexual interest. Grab them by the crotch. Zucker looks entirely pleased with herself, demands to walk in the center and grabs the arms of both men. If that is what is expected and that is the norm in your workplace, how can you be the cold one who keeps her sexuality to herself?
I invite you to contemplate why this got me thinking about Erica Jong's concept of the "zipless fuck":
The zipless fuck is absolutely pure. It is free of ulterior motives. There is no power game. The man is not "taking" and the woman is not "giving." No one is attempting to cuckold a husband or humiliate a wife. No one is trying to prove anything or get anything out of anyone. The zipless fuck is the purest thing there is. And it is rarer than the unicorn. And I have never had one.
