# Sienna Miller Just Gave Corduroy the Best Argument It's Had in Years > At a London exhibition for a brand she's now fronting alongside Idris Elba, the coat did more of the outfit's work than anything else she wore. - Source: Style - Canonical URL: https://style.eu.com/article/sienna-miller-barbour-corduroy-jacket-fall - Author: Style Newsroom - Section: Shopping - Published: 2026-09-18T14:52:07.406Z - Updated: 2026-09-18T14:52:07.407Z - Tags: Sienna Miller, Barbour, Corduroy, Fall Fashion --- Sienna Miller showed up to a Barbour exhibition at London's Saatchi Gallery in exactly the kind of outfit the brand would want her photographed in: their own Antonella Cord Trench Coat, a brown corduroy piece with heritage-style button fastenings and a belted waist, worn over a tartan mini skirt with knee-high boots. Miller currently stars alongside Idris Elba in the brand's promotional film, so the appearance was as much campaign as it was outfit — but the coat is doing enough on its own to be worth separating from the context. Corduroy has been building toward a real fall moment for a couple of seasons now, mostly because it solves a specific problem: it reads as textured and seasonal without tipping into the heaviness of wool or the stiffness of leather. The rib gives a coat like this one visual depth even in a single, muted brown, which is exactly why it photographs as more considered than a flat fabric would in the same silhouette. The styling choice that actually elevates it, though, is the tartan pairing — in Miller's case, a tartan lining inside the coat itself echoed by a tartan mini skirt underneath, which turns what could read as a simple utilitarian trench into something with an actual point of view. It's a formula worth stealing directly: a corduroy jacket or coat as the anchor, one plaid or tartan piece to give it a season-specific mood, and boots to keep the whole thing grounded rather than costume-y. At £319, the coat isn't positioned as an impulse buy, but the styling logic underneath it is the transferable part — corduroy's textured neutral base plus one patterned piece is a formula that works regardless of which specific coat ends up in a closet this fall. --- Originally published by Style.
