US size Medium. Beautifully designed for summer, 'Dionne' has a romantic, vacation vibe. Cut from lustrous duchess satin and lightweight georgette in a smooth espresso hue, the sweetheart neckline has underwired cups to compliment the bust and a corseted bodice to cinch the waist. The ruffled sleeves can be worn on or off the shoulders and we love the ruffled hem for pretty movement. It is fully lined for comfort and has a zip to the back for easy on. No bra required as it’s cupped & lined.
