Rosie HW Swapped Boxy Blazers for a ’90s Single-Breasted Pick

At first glance, the street style scene at this September’s New York Fashion Week felt distinctly familiar—polished denim, directional accessories, sharp tailoring. But look a little closer and you’ll notice subtle styling shifts that signal where trends are heading right now. One of the most telling? The trade of big, boxy, double-breasted blazers for their sleeker, more refined counterpart: the single-breasted blazer.

Spotted dashing across the streets of New York, I noticed actor Aubrey Plaza and model Rosie Huntington-Whiteley swap the once non-negotiable boxy blazer for the chic, seasonal upgrade. Plaza, opting for a glossy leather iteration, styled hers with deep indigo jeans and tall patent boots. The long-line, collarless cut tapped neatly into two of autumn’s other outerwear trends, while a jet-black leather bag rounded her look off with a notably polished edge.

Huntington-Whiteley styled her supple satin style blazer over a sheer chiffon blouse, pairing it with jeans and a sleek black clutch. Creating a pared-back and sophisticated look that felt refreshingly unfussy for Fashion Week.

Where boxy blazers brought volume and drama, these new single-breasted styles channel precision, polish and a refined ‘90s air. With neat silhouettes, button fastenings and collarless designs, they play directly into the sharp, minimalist mood that’s having a moment this season.

My favourite part? This is one of the easiest trends to weave into your wardrobe. Its timeless cut and simple silhouette means that it wears well with denim, as Plaza and Huntington-Whiteley can attest, but looks just as chic with tailored trousers and pencil skirts.
