See Every '80s-Themed Outfit From Netflix's "Stranger Things" Season 4

Eleven pulls from a mix of clothing in season four, including hand-me-downs from Joyce, Jonathan, and Will. Parris says her school clothes are loosely based on Sarah Jessica Parker's character Patty Greene from early-'80s sitcom "Square Pegs," in part because she no longer has Max to assist her with contemporary fashion. "She's a bit clueless and confused by her new style," Parris says. "She's very much having trouble fitting in at high school. She's trying to figure out which clique she should belong to and what her style should say about herself."

Mike — who makes a new friend, Eddie Munson, with his own unique sense of style — is likely influenced by that boldness. He's ready to fine-tune his own aesthetic, and, as Parris imagines, "He is probably picking out his clothing and Mrs. Wheeler isn't choosing his outfits for school anymore."

"Dusty is still in his classic, whimsical flair with fun patterns and functional style," Parris says, explaining that actor Gaten Matarazzo was excited to wear the Scantron T-shirt you'll see this season. "The idea is that Dustin was coloring in the pattern of the Scantron bubbles on his shirt when he was bored in class."

You'll see Lucas embrace his sportier side this season in an effort to fit in with the jocks, so he'll mostly stick to his basketball uniform. Parris describes his looks as a bit more stylish without trying too hard.

"Will is still in youthful stripes and the classic plaids, button-ups, and Wrangler jeans from his Hawkins closet," Parris says. "The Byers do not have a lot of money, so his style is still juvenile and old-fashioned compared to his classmates in California."

"Max is still mourning the death of her brother, Billy, so her style is less fashion and more function this season," Parris says. "Her colors are less bright and cheery from what we have seen in previous seasons."

"Nancy is focusing on herself and her education," Parris says. "She is dressing more maturely and looks effortlessly cool while taking care of business." This season, you'll see her in plenty of collared shirts, denim, co-ord sets, or high-waisted pants cinched and defined at the waist.

"Jonathan is embracing the California lifestyle by wearing more relaxed shirts and clothing with psychedelic patterns," Parris says. "He's been influenced by his new friend Argyle and his 420 lifestyle and enjoys wearing more color this season."

Robin, who Parris says is loosely inspired by "Annie Hall," gets to come into her own style after we saw her in the Scoops Ahoy uniform in season three. Her unique look is a mixed bag of vintage and DIY-style pieces.

Argyle, played by actor Eduardo Franco — who posed here for a fitting photo in a painted button-down, tapered trousers, rainbow tie-dye socks, and mismatched Vans — has a look inspired by '80s surf culture.

Jason — who we generally see in polo shirts, khakis, his varsity jacket, and sneakers — has the typical high school '80s look about him. "He's an iconic jock, making him the perfect villain," Parris says.

Eddie, who becomes a good friend of Mike's, has a look inspired by a young James Hetfield of Metallica. "He's very much a fan of Wizard metal music, like the bands Dio and Iron Maiden," Parris says.
