'T-shirts and jeans are the base of modern dressing,' says Karl Lagerfeld whose line, K Karl Lagerfeld, is in its second season. The Chanel creative director has designed an urban wardrobe of tailored blazers, leather biker jackets, gloss-coated skinny jeans, and fitted t-shirts in a chic monochrome palette. Look out for the graphic K logo on buttons, zips and rivets.
