Black is back, as demonstrated by this long-sleeved minidress from Saint Laurent that nods to the brand's Victroriana references for F/W '18. Cut with a ruffled neckline, this silk style dips dramatically at the back. A drop waist, gathered cuffs and folds at the hemline complete this fail-safe silhouette. Emulate the runway by styling with a headscarf and folded leather boots.
