Agent Provocateur Demelza Full Brief Red. The Demelza brief is a beautiful low-slung brief. It is made from ultra-fine Bobbinet tulle, with crisscrossing rouleaux silk bindings that create geometric panels and placement Sophie Hallette lace motifs. Rouleaux straps meet at the centre of the bottom creating a pretty, framed open look. Satin binding at the waistband completes the look.
