Prada’s laid-back black leggings are accented by a raw-edged appliqué triangle at the side, a signature which echoes hardware on the house’s first pieces of luggage. They’re crafted in Italy from cotton-blend stretch jersey to a slim shape with an elasticated waistband, then accented by a grey logo-woven tab. Add a T-shirt, trench coat and trainers for an unstudied air.
