Ms Miuccia Prada relaunched the house's Linea Rossa line this year, and the technical aspects of the collection seeped into the main line, too. For example, these grey trousers are made from slightly stretchy tech-twill and cut with slim, tapered legs and cropped hems. They're kitted out with four pockets - the front zipped ones are taped - and have pressed creases for a neat appearance. Shown here with Prada polo shirt, Prada jacket, Lanvin T-shirt, Prada sneakers.
