We've all heard of the sacred LBD (little black dress) but it's time to make way for a new champion - the MBD (midi black dress). It doesn't have quite the same ring, but boy does this black cut-out midi dress from Dolce & Gabbana have all the charm. Featuring a sweetheart neckline, a cut out detail, an open back, a rear hook and eye fastening and a rear zip fastening.
