Australian based label Finders Keepers, was definitely inspired by the Cavalli dress for the recreation of their The 'Lose Yourself' dress.
You can purchase the Finders Keepers for $150 at Tobi. Sizing is limited.
There are of course some key differences in the two. The Cavalli dress has an amazing detail sheer lacing on the sides along with the deeper V neckline. Besides the obvious difference of length, the materials/fabrics are different.
