Erdem's 'Tabetha' maxi dress has a sense of drama that'll make you feel even more special at your next event. A brand staple by virtue of its timeless silhouette, it's made from crisp silk-organza, which holds the shape of the sheer blouson sleeves and sweeping tiered skirt. The beautifully embroidered flowers are inspired by the work of iconic '50s florist Constance Spry.
