Sienna Miller and I Agree—This Often Overlooked Jeans Colour Is Actually the Chicest

Here’s something I’ll never quite understand: why fashion people default to blue denim when black exists.

Blue is fine—easy, optimistic, reliable—but black? Black is moody, sexy, flattering and always (in my opinion) just that bit cooler. I’ve got stacks of blue in my wardrobe, but if I want my jeans to do the heavy lifting in an outfit, it’s going to be the black pairs that I reach for. Turns out Sienna Miller feels the same. Spotted in London this week, she skipped the usual red-carpet uniform and turned up in black jeans instead.

To me, black denim sits in this sweet spot between trousers and jeans. It’s elevated without being try-hard, casual, but never sloppy. Wearing hers to a film premiere in London, Sienna paired her inky jeans with square-toe flats, a powder-blue shirt and a rich chocolate-brown jacket. Adding in a roomy tote, and the whole look had an elevated polish that blue denim just can’t touch.

Why black jeans don’t get the hype they deserve is beyond me, but this season, I’m claiming them as my new go-to. Take a cue from Sienna and wear them with sharp shirting and sleek flats, or dial it up with gauzy blouses and heels for after dark.
