who wore it best? sharon stone or miranda Lambert

This gorgeous gown is one of those fashion catch-22's. It's totally memorable, which means we notice the moment someone wears it again.
Sharon Stone stunning in the  +Roberto Cavalli  design during this year's Cannes Film Festival, and +Miranda Lambert  is just as jaw-dropping at the 2013 CMA Awards.
Mr. Cavalli deserves a lot of credit for making a look that works for every woman, and by that, we mean every super hot blonde celebrity with a perfect figure.
