Having been trained at Saville Row, Stella McCartney’s expert and fuss-free tailoring is part of her eponymous brand’s DNA and shows through the Autumn/Winter 218 collection. Crafted from bright-red silk, these flattering wide-leg trousers feature a high rise, an elasticated waistband and side pockets, as well as pressed creases and a delicate piped trim along each side for a leg-lengthening finish.
