One of my picks from Kookai's runway show, was the Positano dress for Derby Day (or as I like to call it "the all black errrrythan day"); so it was no surprise that I have stumbled across a copy cat version from Carla Zampatti.
Kookai's Positano dress retails for $240, and is available in both black and white (this dress dropped in boutiques on Monday - but be quick, they will sell!)
Carla Zampatti's dress retails for $699, and is available in black, navy and white.
