Do you relegate denim to the jeans-only department of your wardrobe? Yes? Well, it might be time to think (and shop) outside the square. This season denim is the fabrication du jour, giving a versatility boost to your favourite off-duty staples. Button-downs are toughened up, dresses get a utilitarian twist and pencil skirts are freed of the office-only vibe. The upside of this denim domination is that coordination becomes a cinch: any colour goes with this hard-working fabric! This season's best newbie denim buys are a mere click of the mouse away. Walk this way. . .
