My wife has this beautiful Carla Zampatti gown is from the SS13 'In The Light Collection' and was purchased for a wedding from David Jones for full retail price of $870.
Only worn 3 times since purchase, has been hanging and unworn for a long time. Always dry-cleaned after wearing. It is a size 10, but it is quite generous. If you're familiar with Carla Zampatti's designs, most people usually go a size down. Will fit a size 12.
