S.Coups, the leader of K-pop group SEVENTEEN, is taking his next steps in his fashion career — quite literally — and making his runway debut by closing out Boss’s womenswear spring-summer 2026 show as part of Milan Fashion Week.

On September 25, 2025, S.Coups surprised fans by doing the honor of closing designer Marco Falcioni’s latest show, rocking the final look from the collection, comprised of a long brown leather trench coat with a matching sheer blouse, black crepe pants with a statement belt, and black shoes.

S.Coups walked alongside models like Ashley Graham, Paloma Elsesser, and more, in front of a star-studded crowd that included David Beckham, Chloë Bailey, Noah Beck, Rudy Pankow, and more.

The show marked another milestone for S.Coups and Boss. The star was named a global ambassador for the brand in April 2025. Shortly after, he made his Met Gala debut wearing a custom look by Boss inspired by traditional Korean clothing. What’s next for S.Coups and Boss? We’ll have to wait and see, given the pace we’re going, and we’d say something big.

S.Coups’s runway debut arrives just days before the star is set to debut under a new SEVENTEEN subunit with fellow member Mingyu. The duo, now known as CxM (SEVENTEEN), will release their first mini-album, titled Hype Vibes, on September 29, 2025.
