When it comes to holiday window dressing, more people are thinking out of the box — and out of the windows — for the brightest displays ever.

Look no further than Hudson Yards, home to Neiman Marcus and a cluster of other stores, which will immerse itself in light and music shows from 5 p.m. beginning on Friday. There’ll be live music and dance performances on Tuesdays, kids’ activities on Saturdays and holiday-themed photo ops practically everywhere you look.

Up on Fifth Avenue, Louis Vuitton has swathed itself in a psychedelic splash of pastel lights, while PayPal — the new kid on the block — is taking window shopping literally: Scan the codes in each of its five windows on West 44th Street off Fifth, and you can buy handmade toys, honey, chocolate and more from a bunch of small businesses.

Some of the best things in store this holiday season are in the stores themselves. Duck out of the cold and lose yourself in enchanting displays in Nordstrom and elsewhere. Read on to find the brightest holiday action in town.

Macy’s

34th Street at Herald Square

Theme: “Believe in the Wonder”

Draws: Macy’s celebrates gal power with its story of Santa Girl, who’s determined to take a proactive role in holiday giving. The loosey-goosey narrative is told through neon lights, multiple Mylar-like Santas and a sweet giant of a dog named Willow, whose big dark nose pokes out of one window. Stroke it, and watch his hind leg come up for a good scratching. Or take the steering wheel at another window and pilot Santa Girl’s truck. As one young boy jerked it back and forth the other day, his mother sighed. “You’ve been in New York too long already,” she said.

Don’t miss: Holiday Lane. On Macy’s ninth floor, just east of the recliners, lies a winter wonderland of trees, ornaments, nutcrackers and stockings. It’s here that you can write a letter to Santa or book (via computer) a visit with the big man himself, now ensconced in Santaland, on the eighth floor. And you thought a table at Rao’s was hard to reserve!

Bergdorf Goodman

754 Fifth Ave., at 58th Street

Theme: “Bergdorf GoodTimes”

Draws: Seven windows filled with old-fashioned frivolity — musical chairs, a slumber party, a scavenger hunt, even a giant pinball machine. A life-size chess game has two glamorous, red- and green-sequined queens going head to head amid a battalion of bishops and rooks, while a card game in another window features a frog splashing into a pond, an ace of spades clutched in one of his webbed feet. Thanks to the dazzling perspective — all these tableaux are viewed from overhead — these are the most dizzying windows in town. “You could look at this for 10 or 15 minutes and still see something different,” marveled Noella Gabriel, a first-time New York holiday-window watcher visiting from the UK. Added one veteran viewer: “You can only get this in New York.”

Don’t miss: The slyly subversive, somewhat spooky windows at Bergdorf’s men’s store across the avenue. In one of them, a male mannequin is being hoisted out of a giant “swag grabber” box like the prize he is.

Nordstrom

225 W. 57th Street

Theme: “Festive Scandinavian Holiday”

Draws: For its first holiday season in New York City, Nordstrom’s elves worked feverishly through Thanksgiving to unveil Friday some 50 miles of twinkling lights, more than 700 Scandinavian-inspired ornaments, 120 trimmed trees and 150 Sputnik-esque chandeliers, like the ones at the Metropolitan Opera. There are also three pop-up holiday gift shops — the one on the first floor featuring curated gifts by RuPaul, Chloë Sevigny and Bill Nye the Science Guy, who personally selected that bow tie. As for that Scandinavian theme: It’s a nod to store founder John W. Nordstrom, who was born in Sweden. Immigrants! They get the job done!

Don’t miss: The daily parades at 6 p.m. (and 2 p.m. on weekends) in which Santa comes ho-ho-ing down the Nordstrom escalator, accompanied by fake snow and a live Dixieland jazz band.

Bloomingdale’s

Lexington Avenue at 59th Street

Theme: “An Out of This World Holiday”

Draws: Bloomie’s marks the 50th anniversary of the moon landing with window after window of space-age displays. In one, robotic arms slowly reach out to grab an ornament and, carefully, automatically attach it to a golden tree: Elon Musk might want to take notes. In another window, several blasé-looking, nonbinary mannequins — imagine the Jetsons, retooled by David Bowie — recline in what’s titled “a Stellar Soiree.” Several windows on the store’s Third Avenue side complete the show, including one with a microphone that lets you karaoke to “Jingle Bells” and a couple of other holiday chestnuts, though not between 7 p.m. and 9 a.m. Judging from what we’ve heard, it’s best to stick to Lexington Avenue, where John Legend’s holiday album plays all through the day.

Don’t miss: Inside the store are Ralph’s Winter Wonderland Polar Ice Bar, a Daily Harvest latte and coffee sampling counter and what, in the shoe department, may well be the world’s largest Ugg.

Saks Fifth Avenue

Fifth Avenue and 50th Street

Theme: Disney’s “Frozen 2”

Draws: You’ve seen the movie — now see the windows! Six beautifully detailed tableaux inspired by the film depict Elsa, Anna, Olaf and friends on a journey through forests, fires and ice. Elsa, the ice queen, gets most of the window time, leading one little girl to ask, hopefully, “Another Anna?” Each window is beautifully wreathed in faux evergreens and twinkling lights. Every night after dusk, the store’s Fifth Avenue facade becomes a light show unto itself, set to a soundtrack of “Frozen” songs and holiday favorites.

Don’t miss: The Enchanted Forest Experience. Up on the ninth floor is an immersive journey through four rooms rife with perky performers, realistic-looking birch trees, lots of fog and — spoiler alert! — a photo op with Elsa and Anna. Timed tickets are $5 at ShowClix.com; proceeds benefit the New York–Presbyterian Children’s Hospital.

Fifth Avenue Association

Four locations, between 56th and 54th streets

Theme: “New York Nostalgia”

Draws: Nature abhors a vacuum, and so does the Fifth Avenue Association. Stung by the loss of Barneys, Bendel’s, Lord & Taylor and other Midtown stalwarts, the group unveiled a quartet of windows to fill in the blank spots — some more Instagram-friendly than others.

Don’t miss: The sprawling faux gingerbread skyline at 689 Fifth Ave. Titled “A Bite for All,” it looks good enough to nibble.
