Stella McCartney borrows codes from traditional tailoring this season, taking cues from the industry's cut, colour and fabric choices. Case in point, this pair of trousers is spun from wool with a hint of stretch in the blend, then shaped to a tapered fit. It's not all classic and formal, though, a slouchy top section and press-stud fastenings offer a comfortable feel and a contemporary look. Wool/Elastane. Colour: green
