How Y2K Comedy "Wild Sing" Used Wigs to Recreate Late-90s K-Pop Nostalgia

Korean comedy film Wild Sing, directed by Son Jae-gon, is pulling back the curtain on how it meticulously built its late-1990s and early-2000s aesthetic—one wig at a time. The production team revealed that roughly 98% of the cast wore wigs to nail the era, an unusually high share even by period-film standards.

Wild Sing follows "Triangle," a fictional three-member co-ed dance group that abruptly broke up after an unexpected incident and unexpectedly gets a shot at a comeback two decades later. The distinct character styling has rapidly become one of the film's main talking points, perfectly channeling a very specific stretch of Korean pop culture that overlaps with the global Y2K revival currently driving modern fashion and beauty trends.

The Triangle members drastically shift looks depending on which era of their career the film is showcasing. For the group's first album, Hyun-woo (played by Kang Dong-won) sports a nostalgic chin-length cut with chunky highlights. Sang-gu (played by Um Tae-goo) wears a tight perm, while Domi (played by Park Ji-hyun) leans heavily into bright, saturated makeup. Together, the trio perfectly reads as fresh-faced rookies, capturing the exact look that filled Korean music television shows at the turn of the millennium.

The second-album era turns the visual volume up even further. All three members add heavy smoky eye makeup to their repertoire. Hyun-woo goes striking silver, while Sang-gu gets a teased-out "bomb head" hairstyle. Domi pairs tight braids with thin, face-framing "antenna" front strands—a signature end-of-century Korean idol detail. After Triangle splits, Sang-gu's solo run gives Um Tae-goo even more comedic and stylistic range, including dramatic dreadlocks and a sleek ponytail.

Meanwhile, Choi Seong-gon (played by Oh Jung-se) has drawn some of the strongest audience reactions and is currently driving a viral social media challenge tied to the film. The younger version of the character carries a moody, chin-length style that nods to the brooding youth stars of the era. The present-day version flips that image completely, featuring rough skin, a thick beard, and long, shaggy hair. Oh Jung-se reportedly pitched multiple ideas for this drastic visual shift himself during pre-production.

To lock in these authentic references, makeup director Jo Tae-hee and makeup chief Kim Na-eun extensively studied the real-life singers and television stars who defined the late 1990s and early 2000s in South Korea. They meticulously built multiple custom wigs per concept and ran exhaustive fitting tests to ensure each look read correctly on camera and matched the specific facial structure of the actor wearing it.

The production noted that the film ultimately used more wigs than a typical Korean historical drama, with about 98% of the cast in hairpieces at some point. The ultimate goal was to give each character a highly individualized identity while keeping the overarching, nostalgic Y2K mood consistent across the entire project.

Wild Sing is currently playing in theaters across South Korea.
