For striking after-hours sophistication opt for Roland Mouret's Amesbury dress. It's crafted with a structured black viscose bustier which meets a pleated skirt featuring the new season's swirling Mexican rose print in silver brocade. The gold-tone metal zip meets a single slit at the back while the black satin lining crops at the knee for a sheer finish. Style it with dramatic heels and a clutch for an elegant evening out.
