Cefinn - Cefinn's emerald-green Freya dress reflects creative director Samantha Cameron's penchant for rich, jewel tones. It's crafted from lightweight voile to a boat neckline and descends to a dipped midi hem that's lined with coordinating crepe, then cinches around the waist with a tie sash. Style it with stiletto heels and a statement bracelet for a special occasion.
