Description from Kookai website:

The Jasmine Maxi Dress delivers effortless elegance with its fluid silhouette and refined details. A plunging halter neckline lengthens the frame, while the softly draped bodice and adjustable sash-style waist tie add shape and movement. The sleek racerback balances the dramatic front, flowing into a full-length skirt that moves beautifully with every step - ideal for evenings that call for a polished, understated look.
