The impact of Saint Laurent’s spring/summer 2025 show is already being felt on the streets with a leather jacket or two. The morning after the night before, Vogue ’s Daniel Rodgers boss-bitched his way into The Adelphi wearing a gently outsized pinstripe blazer as a subtle nod to Bella Hadid’s tailored return to the runway. In Paris, Rosie Huntington-Whiteley and Gigi Hadid have been making slouchy leather jackets the crux of their street-style looks, while models nipping between casting calls are throwing their own bikers over basics on the run.

Of course the leather jacket is not a new wardrobe staple, but something about Saint Laurent’s drop-shouldered, buckled, supple style feels particularly fresh for now. On the catwalk, the popped-collar pieces served as protective outerwear to louche suiting, for a toughened up take on office wear. “You’re dressed.

It’s about control, and power, in a way,” said Anthony Vaccarello of his razor-sharp approach to realising the “relaxed” look. Away from the impossibly glamorous Left Bank headquarters of YSL, the Hadid sisters have been deploying their softly sloping jackets to bring both nonchalance and grit to downtime looks (and Rosalía’s birthday party). No one wants to swan around Paris looking “done”, or as though they’ve curated their fashion week wardrobe – even if, like Rosie Huntington-Whiteley, they have.

A textured leather jacket offers the swagger of that biker lifestyle, but with all the luxury.
