The gat is Korea's traditional black horsehair hat, historically worn by Joseon-era noblemen as a marker of adult status and social rank — and it's become an unlikely global fascination in recent years, largely thanks to a Netflix zombie drama that turned a centuries-old accessory into one of the most recognizable images of Korean period costuming worldwide. What started as a formal, everyday item of aristocratic dress has ended up inspiring international fan art, viral social media reactions, and even a sold-out contemporary ballet built entirely around the object.
What a Gat Actually Is
A gat is constructed from horsehair woven over a bamboo frame, dyed black, and shaped into a wide, flat-brimmed silhouette that sits atop a tall, narrow crown. During the Joseon dynasty, wearing a gat was closely tied to reaching adulthood and social respectability — for a Joseon-era nobleman, or yangban, going out in public without one was roughly equivalent to leaving home without being properly dressed. Because gat were handmade using labor-intensive traditional techniques, finer examples functioned as visible markers of wealth and status as much as practical headwear, distinguishing their wearer at a glance.
How a Zombie Drama Made It Famous
The gat's leap into global pop culture is closely tied to Kingdom, the Netflix period zombie series set in Joseon-era Korea, where noblemen wearing wide black gat became one of the show's most visually distinctive and frequently discussed elements among international viewers. The hat's unusual silhouette — striking, formal, and unlike anything in Western period costuming — became a recurring point of fascination in overseas reactions to the show, turning what was simply accurate historical costuming into an internationally recognized visual signature of Korean sageuk (period drama) aesthetics.
Reinforced by KPop Demon Hunters
That international recognition got a further boost from an unrelated but culturally connected source: KPop Demon Hunters, Netflix's record-breaking animated musical, features the fictional boy group Saja Boys performing in black gat as part of their stage styling, a visual choice that circulated widely on social media alongside the film's broader viral success. Between Kingdom's historical drama treatment and KPop Demon Hunters' stylized pop-culture version, the gat has now been introduced to international audiences through two very different genres within just a few years of each other.
From Screen to Stage: The Ballet "GAT"
That surge of international attention around the gat directly inspired a real-world creative project: Yoonbyul Ballet Company's contemporary work titled simply GAT, which fuses Korean traditional dance and ballet into a single piece built around the visual identity of the hat itself. The production was conceived specifically in response to Kingdom's overseas reception, and performers wearing black gat throughout the piece became a widely shared image on social media following its debut. Since premiering in 2024, GAT has sold out both its original run and a subsequent 2025 national tour, and continued touring six cities across Korea in early 2026, from Hwaseong in February through stops in Daejeon, Busan, Seoul, Hanam, and Jeonju.
