Sienna Miller's stage door style during her run of Cat on a Hot Tin Roof has been near-perfect, but we think the outfit she wore after her performance last night is her best yet. Sienna wore a pair of dark grey, straight-leg jeans with yellow Trademark mules with a feathered corsage on the toes. But it's her jumper that we really want: a pink chunky ribbed merino-wool jumper with a classic round neckline and rolled-up sleeves. If you're suddenly craving a pink knit, below we've put together an edit of the best around from Sienna's Rag & Bone jumper to Finery's amazing high-neck sweater.
