Roland Mouret - Roland Mouret's red Katana dress is designed with a waistcoat-inspired bodice featuring a graceful open back and sultry plunge neck cut out. The halterneck style is rendered in the UK from wool crepe with a gently elasticated waistband and falls into a flowing skirt that's slit at the hem to accentuate the fluid aesthetic. Style it with neutral stilettos to keep the bold colour as the central focus.
