Forget fringe and feathers; forget saying no to fur. It is possible that the biggest trend in fashion is about to become getting rid of all of your … fashion.

Next week Cameron Silver — the founder of the Los Angeles vintage store Decades, famous male peacock, fashion director of H by Halston and its QVC face — will use his store and website, decadesinc.com, to sell off 400 pieces of his own wardrobe collected over the last 35 years. Soon after that, another 100 to 200 pieces will be offered on grailed.com.

This follows the wardrobe auction in February of 30 pieces from the closet/apartment of the street-style star Anna Dello Russo at Christie’s, along with the sale of 150 additional pieces on Net-a-Porter. And that followed the 2008 sale by Daphne Guinness of approximately 1,000 pieces of Chanel, Versace, Valentino and Saint Laurent (among other names) at Kerry Taylor Auctions.

Amid it all were smaller sell-offs by Chloë Sevigny along with Khloé and Kourtney Kardashian, and sisters Kendall and Kylie Jenner, all of whom had special “pop-up shops” on therealreal.com, with the Jenner Kardashians divesting themselves of over 500 gently worn items last year.

The age of the colonic cleanse is giving way to the age of the closet cleanse. You can focus on the bizarre numbers involved and beat your breast about the evolution of a culture in which one is driven to ask, Who needs so many clothes?

Yet while it is a legitimate question, a more relevant one may be: After decades in which fast fashion gave rise to accessible luxury and spurred an accelerated seasonal cycle that in turn spurred a binge of accumulation, be it shirtdresses or sneakers, Supreme or Hermès, are we finally reaching a tipping point?

“I hope so,” said Mr. Silver, who had a wardrobe of “thousands” of pieces scattered between his homes in Los Angeles, New York and Pennsylvania, including, he said, “50 man furs in storage in L.A., and I don’t even wear fur. It’s what I spent money on instead of buying a house in Malibu.”

He still loves clothes, but he has some new mantras, and he regards them with the same passion he once regarded a hot pink Jil Sander by Raf Simons suit. Specifically: “It’s chic to repeat” and “The best new clothes are old clothes.”

“Owning Decades was like opening a weird Pandora’s box for me,” Mr. Silver said. “I was obsessed with clothes growing up, but it was the store that made me a collector. I looked for pieces that represented a season, or told the story of the time we were living in. But then it took over my life.”

It was the joint chronological landmarks of the store turning 21 and a looming 50th birthday (Mr. Silver turns 49 later this month) that served as motivation, he said, “to liberate myself from all these possessions.”

It’s tempting to blame it all on Marie Kondo, and her best-selling book “The Life-Changing Magic of Tidying Up,” and there is something symbolic and cathartic about shedding wardrobes.

Many of the sellers cited personal, emotional reasons for divesting themselves of their clothes: Ms. Guinness sold hers in part as a reaction to the end of her marriage to Spyros Niarchos; Ms. Della Russo did so after the deaths of her mentors Manuela Pavesi and Franca Sozzani, and the beginning of a new relationship. And many, though not all, attached the proceeds of the sale (or at least a portion) to a charity, almost as a form of penance for the indulgence.

But just as the clothes themselves often reflect specific moments in time — Mr. Silver noted that his wardrobe is “an opportunity to see how we got to this men’s-wear-focused moment,” with pieces from designers like Paco Rabanne, Stephen Sprouse, Issey Miyake, Haider Ackermann and Alexander McQueen — the sell-offs themselves may tell us something specific about our particular moment.

They are not, for example, part of the same continuum really as the sales by celebrities like Liza Minnelli and Jane Fonda, which have also become something of a thing but which relate more to Hollywood mythology than fashion (or, say, the recent Russell Crowe divorce auction, which was mostly about the value of his own celebrity, and buying a piece of it).

Instead, the sales by Mr. Silver and his ilk seem more purely related to the current consumer culture. They are products of the way in which visual consumption and the need to fill the digital void with More Crazy Outfits! and Even Wilder Looks! have begun to drive actual consumption to unsustainable levels. Not in the ecological sense, though that is part of it, but in the psychological sense.

It’s a peculiarly contemporary vicious cycle: If your personal brand and your professional brand are increasingly interchangeable, and part of that brand is dressing in a seriously eye-catching way, and that kind of dressing then causes photographers to seek you out and take pictures, that in turn creates pressure to dress more crazily and change more often and get more stuff, which gets more pictures and so on and so on ad infinitum.

“The expectation that whenever I showed up, I would wear something that turned heads or dropped jaws was really strong,” Mr. Silver said. “Every Met Gala had to be a bigger fashion moment, which in turn encouraged me to be extra social and go out like crazy. It was like performance art, but at a certain point I felt like my wardrobe took over my authenticity.”

This phenomenon is what has led on a smaller level to the explosion of the resale market, and sites like Vestiaire Collective, the RealReal and (on a more accessible level) ThredUp, where fashionistas sell their seasonal splurges to make room in their closets and help finance the next ones. On a bigger level, it has created the sell-off situation.

Once upon a time, great fashion plates — Nan Kempner, Jacqueline de Ribes — collected clothes the way they collected jewelry and porcelain and then left them to a museum like the Met’s Costume Institute or the Palais Galliera in Paris, understanding that they would become cultural relics. Now they can divest earlier, and with purpose.

Valerie Steele, the director of the Museum at the Fashion Institute of Technology, said in an email that auctions used to sell only 18th-, 19th- and early-20th-century pieces.

“But now ‘vintage’ means anything more than three seasons old, and even less sometimes,” Ms. Steele wrote. “There is no incentive for collectors waiting until their clothes have ‘aged’ into fashion history, especially when the latest fashions are on display in museums. And it’s certainly true that people (and heirs) increasingly seek to monetize fashion collections.”

Besides, Mr. Silver said, “not every museum wants everything.” Indeed, before he decided to sell off his clothes, he donated a number of pieces to the Los Angeles Contemporary Museum of Art for “Reigning Men,” a show on men’s wear that opened in April 2016.

And it’s not like he won’t have anything left. There are still 300 pairs of shoes, he said, “and suits in 50 shades of gray from pretty much every designer you can name,” since gray suits have become his new uniform. But, Mr. Silver said, “it feels great to be free from the pressure to figure out who’s the hottest new designer or what’s the most important new silhouette.”

It’s a monster of our own creation. But there seems to be a growing (and welcome) consensus that it’s time to cut off its head.
