Dark, crisp and lean: this season's smartly turned out mood calls for seriously sophisticated denim. Look to The Row and Valentino for sharp shapes that will work just as well in the boardroom as over out-of-office sunshine buys; or invest in a cropped, slim-fit style from Calvin Klein or Levi's, best paired with the matching trousers. And if slightly baggier shapes still appeal? Just stick to a deep indigo and you can't go far wrong.
