Park Ji-hyun Steps Into Athleisure Without Breaking a Sweat

She started as a Spanish major at Hankuk University of Foreign Studies—literally walked the campus as a cover model for University Today magazine. That one campus photo somehow became a ticket to everything else. No flashy debut story, just steady work building up. There's Yumi's Cells, Reborn Rich where she played Mo Hyun-min, then Speed to You 493km, and more recently Rich Man x Detective where she led as Lee Kang-hyun. She's built her career by actually acting, not just showing up. That same deliberate energy shows up in how she approaches style, especially athleisure. We've got four looks from her work with Sergio Tacchini sportswear, plus her off-duty street style mixed in.

**Training Fit: Deep Brown Everything**

Start with the Sergio Tacchini training set in deep brown. The crop tank top has that ribbed knit texture with genuine ribbing that actually gives you stretch and support when you're moving around. Pair it with matching brown joggers that have that elastic-cuffed ankle cut that lands perfectly against sneakers. It's tonal, it's cohesive—just one color family carrying the whole look.

Then she throws a hoodie over the whole thing, and that's where the magic happens. Suddenly you can move from the gym to a cafe and not feel obligated to go home and change first. White sneakers punch up the heavy brown tone with brightness and give you visual variety. This is the 'one outfit for multiple settings' formula: brown foundation, then layer in the versatility.

**Summer Sports Look**

Heat it up with a white graphic tee featuring the brand logo with navy ribbed detailing at the collar and sleeve cuffs—that retro athletic vibe, like 1990s gym class but make it editorial. Gray setup shorts paired on top, and here's the key move: she's tucking in the tee to define the waist, which automatically makes your legs look longer. Worth remembering.

Gray hoodie layered over top ties the whole thing together without adding visual noise. White socks pulled up slightly, then sneakers. The color palette is dead simple—white, gray, navy—which means literally anyone can replicate this without overthinking it. This is the outfit you grab on a summer day when you want to look like you have your life together but you're actually just comfortable.

**All-Black Windbreaker Energy**

Now the heavy hitter: full all-black athleisure moment. Matte nylon windbreaker on top with a half-zip cut, black everything below. The windbreaker is thin enough to breathe but solid enough to block wind. The fit is roomy and oversized in that comfortable way, with a stand collar and zipper details that give structure to what could otherwise be a boring black-on-black situation.

Texture becomes the star when you're monochromatic like this. The matte windbreaker contrasted against the smooth pants creates visual interest just through material difference. Wear this over gym clothes or under a coat heading somewhere—it's pure utility meets attitude.

**Off-Duty Street Look**

Burgundy graphic tee with some vintage washing, then a black zip-up hoodie thrown on top for layers. But the real statement here is the leopard print wide-leg pants—bold enough to be risky, but she's keeping the top half quiet in muted tones to balance it out.

The leopard isn't neon or screaming for attention; it's muted enough that the brown tones in the pattern blend with her burgundy tee. It's one strong piece with everything else staying low-key. Brown sneakers ground it even further. This is how you wear a statement-print piece without looking like you're trying too hard—keep the top calm and let the bottom do the talking.

**Her Athleisure Formula**

Whether she's in branded sportswear or pieces from her own closet, she's playing with tone and texture as her language. Deep brown, clean gray, then pure black, then mixing in patterns—but always with restraint on top. She's not trying to be sporty OR fashionable. She's just wearing things that work for her actual life: gym, then cafe, then the streets. There's no reinvention happening, just intention.
