Gen Zs wear bold, tight clothes for ‘Fran Fine’ fashion fad.

The flashy girl from Flushing — the nanny named Fran — is being named Gen Z’s most haute heroine.

It’s The Nanny-core couture, baby!

“She unapologetically extra, glamorous and sexy,” Charissa Mattera, 26, from Bay Ridge, told The Post of Fran Drescher’s role as the irrepressibly fabulous Fran Fine in the 1990s sitcom “The Nanny.”

A fashion plate with chichi taste, the fictional Ms. Fine stole the spotlight of nearly every scene in luxe, look-at-me finery since the show debuted in 1993.

Her colorful ‘fits and skimpy miniskirts often disrupted the beige blandness of the Upper East Side Sheffield residence, where she worked and wowed as a live-in sitter for a rich Broadway producer and his three kids.

And now, almost 30 years since the series ended in 1999, twenty-somethings, including A-listers like Sabrina Carpenter (who was born in ‘99), are reviving her saucy vibe with the Fran Fine fashion fad.

It’s the perfect blend between “stealth wealth” chicness and “mob wives” gangster glam.

“She’s a New York City girl who’s not afraid to dress boldly,” said Mattera, a virtual tastemakerpraising Fine for inspiring her eponymous trend. “Now that the clean-girl and sporty aesthetics have passed, we’re itching for a classic and fun way to express ourselves through fashion.”

And who better to emulate than the lady in red — or animal print, or houndstooths or sequins — when everybody else is wearing tan?

Drescher counts Gen Z’s adulation as an honor.

“I feel blessed that Fran Fine remains so current and influential to so many generations of women and girls, men and boys, and everything in between,” Drescher, 67, told The Post.

“Gen Z watched [‘The Nanny’] on internet outlets, and had a heightened awareness of the fashion and glam that Fran Fine exemplified,” continued the Queens native.

And she applauds Zoomers for transforming social media into a virtual runway.

“They became the generation to take ‘The Nanny’ look and make it their own, leveraging TikTok and YouTube as its main stage,” added Drescher, before hailing the black, leopard-lined skirt suit that she wore on the show’s pilot episode as her “favorite” little number.

It’s a signature ensemble that’s apparently inspired Carpenter’s closet.

The “Please, Please, Please” performer, 25, rocked a nearly-identical, vintage Lillie Rubin two-piece while en route to “The Late Show with Stephen Colbert” in NYC on Dec. 10.

Her buzzy, black-on-black look was elevated by leopard-print accents, including a plushy fur collar and arm cuffs, and three big buttons to match.

Voguish VIPs such as Cardi B — and even Harry Styles — have, too, been lauded for incorporating Nanny Fine’s ‘90s flair into their wardrobes.

But Brenda Cooper, the costume designer behind the production’s iconic togs, tells The Post that those pre-Y2K looks were actually inspired by her love of mid-century fashion.

“My influence has always been the glamour of the 1940s, ‘50s and ‘60s,” said Cooper, who curated most of “The Nanny” attire with actress Katharine Hepburn in mind. “I call the style ID ‘sassy elegance.’”

And Drescher’s hourglass figure served as the perfect canvas on which to mount her artistic visions.

“Fran and I were a match made in style heaven,” the Emmy-winner gushed. “We created outfits with style, wit and humor.”

It’s a glitzy goal Elizabeth Fortmeyer aims to achieve each time she hits local thrift shops for a few Fran Fine finds.

“The best way to shop for ‘The Nanny’-inspired clothes is to shop frequently,” said the 23-year-old Manhattanite, who grew up watching reruns of the sitcom with family.

She routinely snags goodies — pieces from Moschino, Galliano and Carolina Herrera — at hotspots like L Train Vintage and Beacon’s Closet in Park Slope.

“I’ll spend around $150 on a really special designer piece,” added Fortmeyer, a content creator at The Industry Creators. “I feel that’s how Fran would do it.”

Sharon Aguilar Gonzalez, 24, does it that way too, haunting vintage boutiques for bold colors, tight silhouettes and playful patterns.

She just spends more like a wealthy Sheffield kid, rather than their budgeted yet debonair au pair.

“A good $1,000 goes into coats, skirts, two-piece sets, blazers and any fun [article of] clothing that catches my eye,” said Aguilar Gonzaleza home health aid and influencer from Queens.
