Even in a relaxed office environment, where a dress code isn't mercilessly enforced, we've always believed that stepping up your style at work is the easiest way to look like you're on top of your game. The real key to building a smart business wardrobe is choosing pieces that not only look sharp, but are easy to incorporate and feel good as well. Like a proper pair of trousers. Whether cut from cotton, wool or textured cloth like tweed, today's better versions are cut a lot like your favorite pair of jeans and look just as good with lace-up shoes as they do with your hiking boots.
