Yoonchae in burgundy Aritzia Super Puff with brown scarf

Yoonchae is stepping into the spotlight for her latest fashion collaboration, becoming the star of Aritzia’s new Super Puff campaign. The KATSEYE member brings her relaxed but polished style to the outerwear brand’s latest campaign, proving that a winter puffer can be practical without looking basic.

Titled “Get Caught in the Moment. Not The Weather,” the campaign follows Yoonchae as she puts her own spin on Aritzia’s signature Super Puff. The campaign focuses on wearing the puffer through everyday moments rather than waiting for perfect weather, highlighting the jacket’s versatility across different looks and settings.

One of the standout looks from the campaign sees Yoonchae in an icy white Super Puff with relaxed gray trousers. The oversized jacket has a high, padded collar and a softly glossy finish, creating a clean, almost monochromatic winter look. She wears her long platinum-blonde hair loose with a center part, keeping the styling minimal and fresh. In another image, she adds slim black sunglasses, giving the white puffer a more street-style feel.

The mood shifts with a striking deep burgundy Super Puff, which Yoonchae wears over a short black outfit. She adds a huge chocolate-brown scarf wrapped around her neck, sheer black tights and sleek black knee-high boots. The glossy burgundy jacket, oversized scarf and dark accessories make this look feel particularly polished for cold-weather dressing.

And, of course, there is an adorable campaign co-star: Yoonchae’s fluffy Pomeranian, who appears alongside her while she walks through the city and poses in the burgundy puffer.

The campaign also reflects Yoonchae’s personal approach to fashion. Speaking to ELLE, she described her style as “comfortable and effortless”, explaining that she likes simple, versatile pieces that can be styled in different ways. She also said her style has been influenced by both Korea’s polished fashion aesthetic and the more relaxed attitude she has experienced in Los Angeles.

For the new season, Aritzia has expanded the Super Puff into fresh silhouettes and colors, including Mochi Pink and Stormcloud Grey. The brand says the Super Puff uses responsibly sourced goose down and is designed for substantial cold-weather warmth.

As the youngest member of KATSEYE, Yoonchae has quickly become known for her modern, streamlined fashion sense alongside her rising global pop career. Her Aritzia campaign feels like a natural extension of that style—comfortable, youthful and effortlessly cool.
