Winona Ryder pulled out old jeans from her own closet to be used in the latest season of Stranger Things.
The fourth season of Netflix's hit show has been directly responsible for a resurgence in '80s music, with Kate Bush's 1985 track Running Up That Hill racing to the top of music charts all around the world.
The decade's fashions have also become coveted by a new, younger, audience, with Stranger Things' costume designer Amy Parris revealing most of the clothes seen in the show are real retro.
"The show is all about being authentic," she said to Harper's Bazaar Australia. "We even used Winona (Ryder's) own personal '80s jeans from her parents' closet! They were already the perfect amount of distressed and worn-in.
"We avoid using anything new or contemporary unless it's absolutely necessary to have multiples and if we don't have time to make it ourselves...about 90 per cent of the show is vintage or built from scratch."
Amy cited '80s movie icons Molly Ringwald and Ally Sheedy as big inspirations for some of the costumes, but she also heavily researched what school kids from that time period were wearing.
For newcomer Joseph Quinn, who plays Eddie Munson, Amy followed the lead of "dudes who listened to wizard metal like Dio and King Diamond".
"We looked at real kids from the time period," she explained. "I spent lots of time on Classmates.com, which has assorted yearbooks, gathering images of real students in different parts of the country. I also found lots of D&D (Dungeons & Dragons) club group photos which lent lots of inspiration for the Hellfire Club."
