London-based label Erdem is synonymous with elegant cocktailwear, and the Brenton dress is a beautifully crafted piece from his new collection. The streamlined shift silhouette is made from emerald-green wool-crepe, and features a full black stretch-jersey back that sensuously moulds to the spine. Clustered crystal embellishments and a leather-trimmed neckline finish it with couture-like precision.
