An Yujin's Geek Chic Formula: How One Pair of Glasses Changes Everything

Look, geek chic is having a major moment, and if you want to understand what actually makes it work, An Yujin at 173cm tall with that crisp vocal tone and that "intelligent chaos energy" she gives off on variety shows? She's basically the walking textbook.

With those long limbs and an ability to rock literally any silhouette, An Yujin has been quietly mastering the balance between intellectual and cool. Her recent casual outfit content is breaking the internet, and it's not because she's doing anything complicated—it's because she understands a fundamental principle: small accessories can completely reframe a whole look.

① The Geek Chic Starter Pack: Thin Frames & Classic Pieces

Here's the magic formula: take slim, minimalist eyeglasses—the kind with delicate frames that don't overwhelm your face—or go classic tortoiseshell. Pair them with a crisp button-up shirt or drape a neat vest over a tee. That's it. That's the whole move. The glasses alone shift your entire energy from "idol in casual mode" to "intellectual with taste." They make sharp features even sharper, and suddenly your whole outfit reads as intentionally curated rather than thrown-together. The headers and neck detail don't hurt either—they frame your collarbone in a way that keeps things fresh.

② The 173cm Advantage: How Proportions Make or Break Y2K Fits

If you've got the height, you've got a cheat code. An Yujin pairs cropped tees (showing just a hint of waist) with wide-leg denim or baggy silhouettes on the bottom. That contrast creates visual interest without looking messy. And because she's tall, she can wear oversized jackets and athletic wear in a way that still reads balanced, not swallowed. A simple crop and high-waisted wide pant combo instantly looks editorial. Throw in unstructured hair and you've basically got that quiet 2000s magazine aesthetic without the effort.

③ From Sweet to Edgy: An Yujin's Fashion Spectrum Isn't Playing Around

What makes her truly dangerous as a stylist is range. As a Fendi global ambassador, she can step into high fashion and command it. But then she'll pivot to stud-covered pieces and halter necklines for that girl-crush moment, or go full sweetness in overalls and pastels when she wants to feel approachable. She's not locked into one lane—she's fluent in multiple aesthetics and knows when to deploy which one.

The Geek Chic Playbook According to An Yujin

Don't fear the glasses. A pair of slim frames or tortoiseshell is your shortcut to looking put-together without doing much. If the frames feel like too much, start with thin-rimmed styles and build confidence.

Let your proportions do half the work. If you're tall, exploit the cropped-top-plus-wide-bottom ratio. It's an instant vibe. If you're not blessed with height, scale everything proportionally and the effect is still there—it's just about visual balance.

Mix formality and casual without apologizing. A crisp shirt paired with hip-hugging jeans. A luxury tee with relaxed pants. Tailored vest over basics. That collision is what makes geek chic actually interesting.

An Yujin's whole approach to fashion comes down to this: she knows exactly who she is (intelligent, composed, slightly chaotic energy), and she dresses like she's confident about it. Not overthinking it, not second-guessing, just being clear about the aesthetic you're going for. That's the real flex.

If you're ready to test-drive geek chic this season, An Yujin's looking like your north star for how to make it actually work.
