Abstract pewter fil coupé lends Roland Mouret's black organza gown a subtle and modern slant. It's supremely crafted in the UK with an asymmetric one-shoulder neckline that brings the collarbones into focus and falls into a fully flared skirt from a boned bodice. Black silk-organza lining ensures it hangs beautifully. Complete a gala-worthy look with statement earrings and a clutch.
