These midnight-blue velvet trousers from Stella McCartney's Resort 2018 collection offer a sharp way to wear the soft fabric that's in vogue for the season ahead. They're tailored with a high-rise waist, side-seam slip pockets, and kick-flare legs cropped at the ankles. Wear them with the matching jacket, shoulder-skimming earrings, and pointed mules for a confident, unfussy evening appearance.
