What appear to be ordinary brown socks are actually made of pure wool from the vicuña, a protected ancestor of the alpaca that lives high in the Andes and may be sheared only very rarely. To get the socks, you have to make an appointment at the Upper East Side townhouse shop VK Nagrani.

An Early-’80s Diesel Mercedes

“These cars were always a big deal among auto nerds. They are the apex of beautiful indestructible machines, the apex of German engineering. I started noticing them in Williamsburg about three or four years ago. I would say, ‘Oh, there’s another one.’ And when I realized that their engines last literally forever, I immediately got a 1983 300D Turbo Diesel. These days, I see one at least once a day in my neighborhood. It’s kind of like anything else that gets gobbled up by retro-loving hipsters; people think, It’ll look great with my surfboard on the roof. It’s the same reason that these heritage menswear brands are exploding. They’re cool-looking, they’re well made, and there’s a good story. That said, these cars are really vulnerable to rust, and so I recently sold mine — the next big thing are Jeep Wagoneers.”

—Gref Stefano, director and producer

The Uppababy Vista

According to moms on the Bococa Parents Yahoo group.

“The ‘in’ stroller right now is definitely the Uppababy Vista, for sure.”

“Uppababy Vista!!”

“I would say the Uppababy Vista.”

“I think it’s still the Uppababy Vista.”

Beckley

“Beckleys are made of horsehair, and they last — especially if the chambermaids turn the mattresses weekly as they should.”

Clockwise, from bottom left:

A Ted Muehling Necklace: “They’re coveted among my colleagues — people who want to be considered to have a high level of sophistication.” —Susannah Drake, DLANDstudio

Shwood Glasses: “Wooden frames represent this return to natural representations, the perception of authenticity.” —Amir Shahrokhi, SHoP Architects

An Issey Miyake Bao Bao Bag: “It’s highly structured with articulated joints; intuitively attractive for female architects.” —Hayes Slade, Slade Architecture

An Olfa Blade: “Carrying one implies that you’re fabricating the projects yourself; you’re embedded in the whole process start to finish.” —Aleksey Lukyanov-Cherny, SITU Studio

Hagoromo Fulltouch

“We started to find little bits of it years ago, discarded ends,” says Joel David Hamkins, a professor of graduate-level mathematics and philosophy at CUNY. “We gathered as many as we could and finally made out the name, Hagoromo. We realized that a Japanese visitor had been leaving behind the leftovers.” It wasn’t available in the U.S., and shipping costs were exorbitant. But in 2010, Robert S. Landsman, assistant program officer for CUNY’s Ph.D. program in mathematics, sent out a jubilant email to faculty: A Japanese student had returned with Hagoromo for the staff. “Finally our prayers have been answered,” he wrote. The limited supply was divvied up based on teaching load. “Faculty should save this chalk for use only during their most important lectures or when working on their most important theorems,” he cautioned. The chalk was later sold Stateside, but then, last year, tragedy: word that Hagoromo was going out of business. Hamkins — like others — has stockpiled the stuff. “The smooth texture flows so easily across the chalkboard, like a fountain pen,” he says. “One puts up mathematics on the chalkboard as if tracing an idea out in the air.”

Kyosuke Kunimoto

“The clover lapels, the vintage fabrics, the slightly flared trousers — these are not mainstream suits. And you have to go all the way to Tokyo to have them made.”

—Rita Zebdi, Frank Ocean’s stylist

Storm Crux

“Regular bowlers who want to be like the pros are now using the Crux. It’s the inside-core construction that’s important.”

—Dino Chang, owner of Dino’s Pro Shop in Astoria

Obscure and European

“They have to be issued by a European library or research institute, like the Villa i Tatti, Herzog August Bibliothek Wolfenbüttel, or a small museum, like the Fondation Custodia, and I would say the text really can’t be in English.”

—A curator who prefers his name not be in English either

Copies of Lapham’s Quarterly; the “Raymond Pettibon: Surfers 1985–2015” catalogue; Dorotheum catalogues; the “Yayoi Kusama: I Who Have Arrived in Heaven” catalogue. —On the coffee table of David and Monica Zwirner, art dealer and co-founder of accessories brand MZ Wallace

A View From the Bridge, by Arthur Miller; Edie: An American Biography, by Jean Stein, edited with George Plimpton; the “Richard Prince: Fashion 1982–84” catalogue; the “Jonas Wood: Paintings and Drawings” catalogue. —On the coffee table of Bill Powers, art dealer, and Cynthia Rowley, fashion designer

Chem Dog

“If you smoke it, you’ll understand why it’s held in such reverence: It has a citrusy flavor and a real depth to the high. There’s no ceiling. If you keep smoking, you keep getting higher. It’s super-rare, because it’s hand-trimmed and has to be grown, harvested, and dried in smaller quantities. You have to know and trust your grower. I’d stick with the East Coast.”

—Danny Danko, senior cultivation editor at High Times

For associates: Rolex

“After your first bonus.”

And for VPs: Patek Philippe

“At this stage, especially if a guy’s done time in a European office, it’s slim watches by Patek Philippe or Cartier.”

And for the CEO: Swatch

“Lloyd Blankfein wears one. And you see other high-level guys wearing them; they have nothing left to prove.”

—A former Goldman Sachs trader

Manic Panic

“It’s trendy now to have a makeup line with goth colors, like the one by Kat Von D. But Manic Panic lipstick is one of those secrets of the streets; you can find it downstairs at Trash and Vaudeville right by the cash register. All of my friends from GHE20G0TH1K wear it.”

—Venus X, DJ and founder of the party GHE20G0TH1K

The Columbia

“The Columbia jacket, from Langlitz Leathers in Portland, is very heavy-looking and shiny, so everyone knows when you have one. They start at $1,100, and they’re really only for going to leather events like Folsom Street East. It’s all word-of-mouth.”

—Jon Fulton, longtime leatherman

Built On-site

“It’s a real status move to have your designer dream up a couch that fits the room so precisely that it has to be custom built in the living room itself over several days.”

—Interior designer with tax-sheltered clients

The Coffin

“I started seeing a lot of girls in this neighborhood wear this style of nail called the Coffin, which is a square shape but slimmer than usual, sexy but not too sexy, so I started getting it too. My friends and I don’t do nail art; we like simple. We wore Coffins in nude colors and pinks for the summer, and we’ll start switching to deep reds and purple in the fall.”

—Renea Scott, 23, client at Barry’s Beauty Bar in Flatbush

Huge

Consider the Tribeca Great Dane: three feet tall, 200 pounds, sturdy and solid as a Citi Bike, visible from an avenue away. To see a dog of this size — whether Dane or mastiff or Bernese mountain dog — is to all but see the apartment it lives in: square feet in the quadruple digits, outdoor space, maybe the keys to the Rhinebeck house nestled in an Alessi vide-poche. We might not know that dog’s name, but we do know everything there is to know about the woman on the other end of that leash — not her personality or likes or dislikes or hopes or dreams, but whether she lives in a private-keyed elevator loft. Such dogs cannot be returned in the morning, nor can they be lent to a friend. They’re not just a sign of wealth, they’re a sign of stability. And whereas, say, a pair of fur-lined Gucci loafers reek of called-in favors and wait lists, a dog the weight of two Gucci PR assistants reeks of … well, dog. It’s an “It” accessory above tackiness, beyond reproach, impervious to changing trends. The Duane Street Dane eats those fur-lined loafers for breakfast.

—Juli Weiner, writer, Last Week Tonight

A Detached House

“Ask any young couple here — the dream is to own a detached house. The one I grew up in shares a wall with a doctor’s office.”

—Rossella Rago, host of the web series Cooking With Nonna

Loree

“You’ll see a lot of oboists using cane from China, which isn’t always aged properly. Top oboists make their reed from Loree cane, which comes from the south of France. The breeze off the water gives it a special vibration. There’s a richness to this cane that’s very juicy.”

—Liang Wang, principal oboist, New York Philharmonic

Ramp Capers

“They are really only good for around a week and a half, so serving them showcases a chef’s relationship with the farmers. Anyone can buy truffles if they have enough money.”

—José Ramírez-Ruiz and Pamela Yung of Semilla

Grether’s Pastilles

“When someone pulls a tin out of their bag, there is a 75 percent chance that they are involved in the theater. They are like magic beans for your vocal cords. You can buy them at fancy places, and when they’re running low you tend to hoard them.”

—Annaleigh Ashford, actress

Pins, Patches, Charms

“Small accessories — pins, patches, necklaces — are a way people try to be individual in our school. I have a Lucky Strike pin that was made for me by another student. We made the pins in class using a machine meant for actual classwork, then made a bunch of other pins for fun on our own.” —Ophelia Sniffen

“I move the Lucky Strike pin that Ophelia and I made to every jacket I wear. And I have this patch from the movie Alien. I’m kind of a movie and sci-fi geek. I wear it on the left arm of my Carhartt jacket.” —Dan Castranova

“One pin I like a lot is this big one-inch button with a picture of Sarah Palin giving a thumbs-up. On top it says, ‘America, Fuck Yeah!’ ” —Sophia Nearhood

“I have a jacket that’s covered in cartoon-character patches. I also wear a bunch of handmade charms and necklaces made from classic toys, like chains with Etch A Sketches and Lego on them.” —Caleb Shelton

“I have this patch that’s a portrait of a friend with the tag ‘Hot Babes’ on it. It’s mostly an inside joke. My friend made it after our silkscreen final with a silkscreen and photo-emulsion stencil.” —Jared Diaz

“Last year, I made a bunch of pins that were stills of Tim Curry’s face in Home Alone 2. We have this hand machine in the communications-design lab, and once our teacher showed us how to use it, everyone went pin crazy. When everyone saw that pins were being homemade, they started asking where they could get them. But only the communications-design students had access to the machine.” —Robert Brackett

Section 7, Row AA, First Few Seats

At Barclays Center.

The Back Nook at Estela: President Obama, when he dined here, sat at the large table in the back nook by the kitchen.

The Side Nook at Polo Bar: Big shots sit in one of two side nooks, off the center of the room, where there are good views and some privacy. The far ends of the room: Siberia.

Bikes 23 and 15 at Stevie’s Wednesday-Night Noho Class

A.k.a. “the Dueling Banjo seats.” According to avid cycler Sydney Friedman, “Getting these are impossible. When a song with a heavy beat comes on, with these two bikes looking right at each other from across the room, it gets competitive.”

Far left: The Chandigarh Armchair by Pierre Jeanneret

“In the ’50s, Pierre Jeanneret and his cousin Le Corbusier created the capital city Chandigarh from the ground up. They were responsible for every single object. Recently, the Chandigarh Armchair has fetched high prices at Christie’s auctions, and I’ve sold them to clients like Kourtney Kardashian, who seems to be following Kanye’s fondness for all things Chandigarh.” —Patrick Parrish, owner of the eponymous design gallery

But in the ... late 1600s: A turned armchair

“We think this chair belonged Jacobus Strijker. A family of their stature would probably have one of these chairs, for the head of the household.” —Alyce Perry Englund, assistant curator of American Decorative Arts at the Metropolitan Museum of Art

... 1780s: A Rococo Chippendale–style armchair

“Among the upper class, tea parties were all the rage in the late 1700s. This armchair was part of a larger set that sat in the parlor of a Wall Street home, which was the most coveted neighborhood at the time.” —Englund

... 1810: A Duncan Phyfe side chair

“Phyfe’s status was such that elites would visit his workshop to check on the timeline of their pieces and be kept waiting for hours before being told that Phyfe was too busy and to try again tomorrow. The next day, he’d simply say, ‘Your furniture will be ready when it’s ready.’ ” —Carswell Berlin, antique dealer

... 1960s: An Eames lounge and ottoman

“Sure, there were more expensive chairs but in the 1960s, this was the chair to own if you wanted to be known as someone with good taste.” —Frank Daley, furniture dealer

... 1980s: A Robert Venturi “Chippendale” chair for Knoll

“I remember walking into a loft designed by Robert A.M. Stern and thinking, What is that?! They were in the ­lobby of the Lipstick Building, in Wall Street boardrooms, in lots of ­apartments. I am sure a lot of people ­privately thought they were ­hideous, but the status of having an artistically driven piece won out.” —Jim Walrod, interior designer

Set of Six Magazines: “Six, Comme des Garçons’ free magazine, was given out to customers from 1988 to 1991. Collectors don’t often want to part with them, making the full set a kind of badge of honor for hard-core Rei [Kawakubo] fans.” —David Owen, co-founder of Idea Books

Polo Ralph Lauren Snow Beach Jacket: “Worn by Raekwon in the 1994 ‘Can It Be All So Simple’ video, it’s a piece that brings up a nostalgia for a time when it was still dangerous to walk the streets of New York dressed well. Its rarity — Ralph Lauren never rereleased it — plays into the hype, with jackets going for thousands of dollars when they show up on eBay.” —Dallas Penn, Polo collector

’90s Memorial Tees: “Featuring Aaliyah, Kurt Cobain, Notorious B.I.G., and other deceased rappers and musicians. This shirt was a very popular limited-quantity run produced right after Cobain’s death in 1994 — and arguably the most sought-after from that era.” —Brian Procell, owner of the Procell shop on the Lower East Side

Arbois Pupillin by Maison Pierre Overnoy

“A few years ago, this wine was very hard to sell. Now restaurateurs are begging for even two bottles. Because wine from the Jura has become popular with young sommeliers, and the label is easily identifiable, Instagramming it shows you’re in the cool kids’ club.”

—Justin Chearno, wine consultant for the Four Horsemen

The G650

“They have a three-year wait list, they start at $65 million, and that’s before you go to town customizing them. These are for people who love design. They are the Apple Hermès watch of planes.”

—Ken Fulk, home and plane decorator

The Dimchae

“They’ve only been available in the U.S. for a short time, and the freestanding version, which has three separate compartments for storing kimchee, is the best. Ideally, you get one in addition to your regular fridge. It says that you have room in your house for two full-size refrigerators.”

—Hooni Kim, chef at Danji

Dalton: Free City Sweatpants

“Girls will wear them around finals. It kind of has that ‘I just rolled out of bed’ look, but these pants cost like $150.” —Aria Dasbach, senior

The Beacon School: Not Wearing a Bra

“It’s a way for feminists here to show they don’t care what anyone thinks of them.” —Alma Bradley, junior

Fieldston: Cartier Love Bracelets

“Kids are more reluctant to be showy at school, so you see these bracelets more on Instagram, or when people go out. You’ll see a lot of girls making a point to make the bracelet visible on Instagram.” —Sarah Hirschfield, senior

La Guardia School of the Arts: Yumiko Leotards

“Everyone wants these — they make your figure look longer and the fabric feels nice, and they are really expensive.” —Xenia Nelson, class of 2015

Bronx Science: Black Iced Coffee

“People are always talking about coffee. It’s a way to show you’re sleep deprived and that you stayed up late working.” —Emily Komarow, senior

Central Park East II: A Limited-Edition Shopkin

“Limited editions like the Apple Blossom are special. Swiss Miss is more common; she’s a cheese, and I’m sort of meh to her.” —Fiona, third-grader

Churchill School and Center: Far Cry 4 for PS4

“I play that game with Owen and Sean, who are the most popular kids in the school.” —Will, sixth-grader

Grillworks

“All the hot chefs who use wood-fired grills have a custom Grillworks grill by Ben Eisendrath: George Mendes, Seamus Mullen, Marc Murphy. Using a wood-fired grill in a restaurant is even more of a status symbol because it means you have the permit to do so, which is about as rare as a key to Gramercy Park.”

—Josh Capon, chef and partner, Lure Fishbar, Bowery Meat Co., El Toro Blanco

Dolly Cohen

“You can tell a Dolly Cohen grill because of the art behind it; she started the movement of only having one gold piece in between the two front teeth. It’s actually not that difficult to track her down — you can find her email address online — but she just won’t respond if she’s not into it.”

—Ian Isiah, Hood by Air ambassador

Clockwise: Rihanna, Rita Ora, M.I.A., Cara Delevingne

A Jeremy Scott x Longchamp Weekender

“It shows you’re important enough to sit front row at a Jeremy Scott show — they’re only given out to people in those seats, and they don’t go on sale for another six months. They always have a print from the collection he shows that day, so you’re a season ahead of everyone else.”

—Noah Johnson, Details’ fashion features editor

The Mandarin Oriental, or the Pierre, or the Plaza.

“People say they want offbeat places now, but the fact is these hotels will transform into anything you want, whether it’s an enchanted garden or a basketball arena.”

But in the … 1980s: Maxim’s

“Maxim’s was very French. New York had not seen anything like this. It was always packed. You had to book your bar mitzvah there way, way in advance.”

… 1990s: The Rainbow Room

“So Old World, so spectacular. It is gorgeous, fabulous, wonderful. I did a ton of bar mitzvahs there.”

… 2000s: Cipriani Club 55

“We did a Moroccan bat mitzvah there. We had a real camel out front. I swear. These people. You can’t make this stuff up.”

—Party planner Harriette Rose Katz

The Jacket: “Custom Charles Ancona.”

‘Blow-Up,’ in Polish

“It’s eye-popping and wonderfully esoteric.”

—Stanley Oh, gallery manager at Posteritati

A Stack of Sidney Garber Rolling Bracelets

“They announce that you’re friends with Sidney Garber designer Brooke Neidich, who’s a big-deal art philanthropist. I actually have a set, and people come up to me and will be like, ‘Oh, how do you know Brooke?’ ”

—Stellene Volandes, Town & Country jewelry editor

A Pair of Noor Fares Gray-Agate Wing Earrings

“Noor is close friends with aristos like Eugenie Niarchos, also a jewelry designer, and they trade each other’s stuff. Another friend, Beatrice Borromeo, just wore Noor’s earrings to her wedding. So having these earrings implies that you’re part of this group of friends.”

—S.V.

Copiapoa

“All copiapoa plants originally came from the Atacama Desert in northern Chile, but stopped reproducing years ago, so any living copiapoa is the last of its kind. Getting a mature one is all about who you know.”

—Carlos Morera, co-owner of L.A.’s Cactus Store

A Prototype of the Lily

“Anyone who has one this early is either one of their investors or an Olympic snowboarder they hired to do promo. It follows you in the air, and the footage makes your life look like a video game.”

—Cody Brown, tech entrepreneur
