Osman Yousefzada is reinventing the little black dress

The perfect wardrobe, we are often told, is built around a core of garments known as "investment pieces". Expensive, timeless and perfect-fitting, the theory goes that these items will carry us seamlessly from one season to the next with the help of a judicious update in the form of a chunky bangle here, a platform wedge there. Jeans are one example of these elusive basics, the white shirt another, but it is surely the little black dress (LBD) that tops the list of sartorial priorities.
