At the opening ceremony of the 30th Busan International Film Festival (BIFF 2025), Kim Yoo-jung became the unexpected center of attention — but not for the reasons fans usually expect. Known for her fresh, doll-like visuals and long-time title as Korea’s “Nation’s Little Sister,” the actress shocked the crowd with a noticeably different appearance that quickly became a hot topic online.

Kim Yoo-jung appeared on the red carpet with her hair left down naturally, but it looked thinner and less vibrant than usual. Her makeup also drew criticism, with many netizens pointing out that her face seemed less radiant and softer compared to past appearances.

The biggest controversy, however, came from her outfit. The gown featured a fully covered top that even hid her arms, paired with a bold high slit on the bottom. Instead of looking elegant and chic, the style was widely described as making her appear older than her actual age.

The stark transformation led to a flood of online comments:

  • Who styled her like this?
  • Where are her arms? This dress is so confusing.
  • Even her hair looks weak… she doesn’t look like the Kim Yoo Jung we know.
  • This outfit just doesn’t suit her — it makes her look way older.

While some defended her attempt at trying a more mature and bold look, most agreed the styling didn’t highlight her natural charm.

Despite the divided opinions about her visuals, Kim Yoo-jung is at BIFF 2025 for more than just the red carpet. She is promoting her upcoming drama DEAR X, where she plays Baek Ah-jin, a glamorous top star with a manipulative, dangerous side. The role is considered one of her most challenging yet, pushing her away from her longtime sweet image into a darker, more complex character.

Critics say this project could be a turning point in her career, giving her a chance to shed the “child actress” label once and for all.
