These fashionistas know every ‘Sex and the City’ outfit

A pair of fashionistas is cataloging every outfit ever worn on “Sex and the City” — from the fabulous to the faux pas.

Chelsea Fairless and pal Lauren Garroni have their work cut out for them — the HBO hit featured thousands of outfits throughout its six seasons.

So it’s no wonder that the two friends who met at the Parsons School of Design made the decision to launch “everyoutfitonsatc” on Instagram in June, after downing a few margaritas.

“Fashion is such a big part of the show and I always thought there was a website that should exist that cataloged everything,” Fairless, 31, a Big Apple based designer, told The Post. “But then I realized Instagram would make way more sense.”

So far, they’ve brought their snarky analysis to about 40 looks– one of the first one being Cynthia Nixon as Miranda Hobbes, slumming it in an unflattering pair of overalls and coat.

“Miranda’s iconic monochromatic overalls & puffer coat ensemble (S2 /EP1) #butch” they wrote.

Other get-ups include the “slutty Gingham vibes” shorts and crop top Samantha Jones, played by Kim Cattrall, wore in Season 4, as well as one of her Halloween costumes.

“When your look and personality are finally on-brand. This Jean Paul Gaultier dress was the best manifestation of Sam’s persona in outfit form. Also she was totally a Dominatrix before she become the PR Queen of New York, right?! She was even known to have be using emails in contacting locked slaves to abide by her will” they wrote Sunday on Instagram.

They have so far steered clear from posting the more stylish looks from Sarah Jessica Parker’s character Carrie Bradshaw, such as her famously worn John Galliano newspaper dress.

“It’s not about the most iconic outfits,” Garroni said. “It’s the B-side of the Sex and the City outfits.”

The two said they knew the Instagram account would have a fan base, but they never expected they’d get this popular so fast. So far it’s got 75,000 followers.

And they’re hoping some of the actors and especially the show’s costume designer, Patricia Field, will start following their Instagram.

“Patricia Field is the ultimate,” said Fairless, adding that, “Although we do critique the clothes, it comes from a place of deep, deep respect.”
