“Little Fires Everywhere” is capturing everyone’s attention with its dramatic twists and nostalgic duds.

The Hulu show — which stars Reese Witherspoon and Kerry Washington and was adapted from the 2017 novel of the same name by Celeste Ng — is set in 1997, with the wardrobe to prove it.

Veteran costume designer Lyn Paolo outfitted the residents of Shaker Heights, Ohio, in authentic pieces from shows she previously worked on, according to Fashionista — including an actual sweater that Julianna Margulies wore on “ER.”

Witherspoon’s children sport plenty of puka shell and choker necklaces, slip dresses, butterfly clips and other looks inspired by “Full House,” “Buffy the Vampire Slayer” and “Step by Step,” the latter of which Paolo worked on.

While most viewers likely experienced the ’90s firsthand, however, the young cast members have no reference point.

Eighteen-year-old Jordan Elsass, who plays hunky eldest son Trip Richardson, told Page Six Style that his least favorite part of the experience was growing out his sideburns. “The day we officially totally wrapped, I went straight home and got out the razor,” he said.

Megan Stott, 16, was a fan of her character Izzy Richardson’s signature Doc Martens, but had trouble wrapping her mind around the concept of pagers.

But even if some of the fashion trends proved puzzling, both Elsass and Stott were big fans of the era’s music, including Nirvana and Alanis Morissette.
