In Genius Girlfriend Episode 9, the visual tone shifts squarely into high school athletic minimalism, dominated by crisp white polo shirts, color-blocked track jackets with contrast shoulder stripes, and relaxed athletic pants. While the exact production brands for the characters' on-screen uniforms have not been officially confirmed, we have broken down the standout silhouettes and curated accessible, similar styles so you can easily recreate these sporty, nostalgic campus looks.
Athletic Uniform Minimalism: The Classic Collared Polo
The primary visual anchor in this episode is the school's athletic polo uniform worn by Lin Zhixia and Zhang Yubai. It is a straightforward, clean design: short sleeves, a flat pointed collar with subtle navy tipping, and a relaxed straight cut through the torso. Paired with deep burgundy athletic track pants, the stark white shirt brings a crisp contrast that feels grounded in practical campus life rather than high-concept fashion.

If you want to pull this clean collared look into an everyday wardrobe without looking like you are heading to gym class, fit is everything. The on-screen shirts have a slightly boxy, loose drape that looks best when balanced against structured bottoms. Try tucking a crisp collared top into high-waisted dark denim or relaxed pleated chinos. For a similar collared silhouette that offers clean lines and lightweight cotton comfort, you can check out the Gleeivy women cotton collared button-down shirt — similar style .

Retro Track Jackets: Sleeve Stripes and High-Collar Zips
When the students step outside or move across campus, they throw on the zip-front uniform jacket. This piece does the heavy lifting for the episode's retro athletic aesthetic. It features a light heather grey body, a tall funnel collar that looks great halfway unzipped, and dual racing stripes in deep navy and crimson running straight down the raglan shoulders.
What makes this jacket silhouette work so well on screen is the contrast between the sharp shoulder stripe and the dropped seam. Zhang Yubai wears it unzipped over his collared polo, letting the collar of the inner shirt spread naturally over the jacket's neck. That two-collar layering gives a casual outfit instant structure.

To recreate this vintage sportswear energy with a slightly dressier spin, consider swapping the nylon zip jacket for a structured knit polo that mimics the muted grey hue and clean neckline. The COOFANDY grey long-sleeve knit polo — similar style delivers that exact sporty collar aesthetic with soft, textured knit fabric that pairs effortlessly with tailored trousers or casual cargo pants.

Off-Duty Layering: Heather Grey Hoodies and Relaxed Casuals
Outside the structured school environment, Shen Fuxian breaks away from the formal uniform aesthetic, leaning into street-smart, relaxed layers. In the evening confrontation scene, he wears an oversized heather grey zip-up hoodie over a dark forest green crewneck shirt.
The styling choice here is subtle but deliberate. The open zipper creates vertical lines, while the high contrast between the muted grey fleece and the deep green base layer adds visual weight without requiring loud graphics or heavy accessories. For anyone building a casual capsule wardrobe, pairing neutral grey outerwear with deep earth tones is an easy formula that always lands.
As the story progresses into later school terms, the styling gradually shifts toward sharper suiting and layered tailoring, which you can explore in our breakdown of Genius Girlfriend Episode 20 Outfits: Lin Zhixia’s Tailored Blazer and Layered Workwear as well as the later wardrobe changes in Genius Girlfriend Episode 24 Outfits: Lin Zhixia and Zhang Yubai Style Guide.
