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 trim pair of trousers. Whether cut from crisp cotton, a light wool or even linen, today's better versions are cut a lot like your favorite pair of jeans and are just as comfortable.
