BOSS taps Corey Mylchreest and S.Coups for its spring-summer 2026 campaign. Captured by photographer Mikael Jansson against a sun-drenched all-white set, the advertisement asks its cast to define what it means to “Be the Next” BOSS.

Mylchreest, riding the momentum of Netflix’s “Queen Charlotte: A Bridgerton Story” and the political thriller “Hostage,” moves through the campaign in a generous mocha double-breasted suit worn open over a dark tank, then shifts to a sand bomber layered over white jeans with tonal runners and an olive duffel.

S.Coups returns to BOSS after fronting last season’s campaign, and the spring-summer advertisement makes the case for why the partnership keeps making sense. The Seventeen leader works an all-sand-to-white palette across both looks, pairing a textured knit polo with wide pleated trousers and a camel perforated tote in one image, then a rich suede jacket over a linen shirt and white trousers in another.

Mylchreest and S.COUPS share the same generous silhouette language but occupy completely different energy frequencies, and that gap is the whole point. Being the next BOSS, it turns out, has no single face.
