I’ve been in the industry long enough to develop a handful of hard-and-fast personal style rules. Every now and then, though, I’m pleasantly surprised when one of those self-imposed limitations is challenged. This morning, that’s exactly what happened.

Stepping out for a walk through Notting Hill, Margot Robbie resurrected a trainer trend I was convinced we’d seen the last of. Better still, she paired it with the one denim silhouette I’ve always found trickiest to style—creating, in one fell swoop, a look that felt modern and persuasive enough to make me rethink my own approach to denim.

Spotted strolling hand-in-hand with her husband, Margot wrapped up against the winter chill in a slate-grey knit, a longline leather coat and a bright red beanie. Cosy, chic and entirely wearable, it was an outfit I could easily see myself recreating. But it was her denim-and-trainer combination that really caught my eye.

Margot stepped out in a pair of high-top Converse, the likes of which I haven’t spotted out and about for several seasons—yet I still have at the back of my wardrobe—styled with cigarette jeans. I’ve long struggled with cropped denim; the shortened hem can visually cut off the leg, and I find getting the right shoe pairing feels particularly tricky. Yet, Margot’s ankle-covering high-tops created a fluid, cohesive line that felt relaxed but cool—proving the silhouette can be far more flattering than I’d given it credit for.
