Slim and sharply tailored, the cigarette pant is a fashion classic that is enjoying some serious cutting-edge fashion credentials right now. Smart and sophisticated enough to wear to work, but equally at home on a night out with a pair of killer heels, these versatile trousers are your next investment. Simple options in monochrome are the easiest way to wear these, or find a patterned pair and stay a step ahead of the fashion crowd. River Island and Missguided do everything from pastels to patterns. Rachel Zoe's cropped options flash ankle, or go for Alexander McQueen for razor sharp style.
