Free shipping and returns on Katie May 'Mykonos' Twist Front Crêpe de Chine Mermaid Gown at Nordstrom.com. A twisted detail gathers and shapes the plunging décolleté bodice before releasing a cascading panel of filmy chiffon down the front of a long, fitted crepe gown that bursts into a godet-flared mermaid skirt. A deeply cut open back ensures your exit is as memorable as your entrance.
